  • Solar System | SPACELIA

    Solar System, The Multi Planetary system in a Milky Way Galaxy, Where our beautiful home Earth exists and other 6 planets as well as, Solar System has a core star, and it operates with the energy of this Star called the Sun. Solar System Interesting facts and information about object of our solar system. SUN Star at the Center: The Sun is a star located at the center of our solar system. It is an enormous, nearly spherical ball of hot plasma that generates energy through nuclear fusion. Source of Light and Heat: The Sun radiates immense amounts of light and heat, which provide energy for life on Earth and drive weather patterns, ocean currents, and the climate system. Composition and Size: The Sun is primarily composed of hydrogen (about 74% of its mass) and helium (about 24%). It has a diameter of about 1.4 million kilometers (870,000 miles), making it approximately 109 times the diameter of Earth. MERCURY Closest Planet to the Sun: Mercury is the closest planet to the Sun in our solar system. It orbits the Sun at an average distance of about 57.9 million kilometers (35.98 million miles). Small and Rocky: Mercury is the smallest planet in our solar system, with a diameter of about 4,879 kilometers (3,032 miles). It is a rocky planet, similar to Earth's Moon, with a surface covered in craters, cliffs, and plains. Extreme Temperatures: Due to its proximity to the Sun, Mercury experiences extreme temperature variations. The side facing the Sun can reach scorching temperatures of around 430 degrees Celsius (800 degrees Fahrenheit), while the side facing away from the Sun can plummet to freezing temperatures of about -180 degrees Celsius (-290 degrees Fahrenheit). VENUS Earth's "Twin" Planet: Venus is often referred to as Earth's "twin" because it is similar in size and composition. It is the second planet from the Sun and is the closest planet to Earth. Harsh Atmosphere: Venus has a thick and toxic atmosphere composed mainly of carbon dioxide with clouds of sulfuric acid. This dense atmosphere creates a runaway greenhouse effect, making Venus the hottest planet in our solar system, with surface temperatures averaging around 462 degrees Celsius (864 degrees Fahrenheit). Shrouded in Clouds: The atmosphere of Venus is perpetually covered in thick clouds that create a highly reflective layer, making it the brightest planet visible from Earth. These clouds consist mostly of sulfuric acid and contribute to the intense greenhouse effect and the planet's high surface temperatures. EARTH Third Planet from the Sun: Earth is the third planet in our solar system, located between Venus and Mars. Habitable Planet: Earth is the only known planet to support life. It has a diverse biosphere with a wide range of ecosystems and millions of species, including humans. Blue Planet: Earth is often called the "Blue Planet" because about 71% of its surface is covered by oceans, which contain most of the planet's water. Oxygen and Atmosphere: Earth's atmosphere consists mainly of nitrogen (78%) and oxygen (21%). The presence of oxygen enables the survival of aerobic organisms, including humans. MOON Earth's Natural Satellite: The Moon is Earth's only natural satellite. It orbits around our planet at an average distance of about 384,400 kilometers (238,900 miles). Lunar Phases: The Moon goes through different phases as seen from Earth, caused by the changing positions of the Moon, Earth, and Sun. These phases include New Moon, First Quarter, Full Moon, and Last Quarter. Lunar Surface: The Moon's surface is covered with craters, mountains, and plains. The darker areas are called maria, which are large, flat plains formed by ancient volcanic activity. The lighter areas are highlands, composed of mountains and impact craters. Synchronous Rotation: The Moon is tidally locked with Earth, meaning it always shows the same face to us. This phenomenon is known as "synchronous rotation" and is a result of the gravitational interaction between Earth and the Moon. MARS The Red Planet: Mars is often called the "Red Planet" due to its reddish appearance, caused by iron oxide (or rust) on its surface. It is the fourth planet from the Sun in our solar system. Similar to Earth: Mars is a terrestrial planet with similarities to Earth. It has a thin atmosphere primarily composed of carbon dioxide, polar ice caps, seasons, and a day length similar to Earth's. Exploration and Potential for Life: Mars has been extensively explored by robotic missions. Scientists are interested in Mars because it might have had conditions suitable for life in the past, and future missions aim to search for signs of past or present life on the planet. CERES Largest Asteroid: Ceres is the largest object in the asteroid belt between Mars and Jupiter. It is classified as a dwarf planet and is the only one located in the inner solar system. Composition and Size: Ceres is composed mostly of rock and ice, and it has a diameter of about 940 kilometers (590 miles). It accounts for about one-third of the total mass of the asteroid belt. Water Ice and Possible Subsurface Ocean: Observations from spacecraft have revealed that Ceres has significant amounts of water ice on its surface, particularly in its polar regions. There is also evidence to suggest the presence of a subsurface ocean beneath its icy crust. ASTEROID BELT Location: Asteroid belts are regions of space located between the orbits of Mars and Jupiter. The main asteroid belt, the most well-known and studied, is found in this region. Composition: Asteroid belts primarily consist of asteroids, which are rocky and metallic objects. These asteroids can vary in size, ranging from small boulders to large bodies several hundred kilometers in diameter. Origin: Asteroid belts are remnants of the early solar system's formation. They are composed of materials that did not coalesce to form planets due to the gravitational influence of Jupiter's powerful gravity. JUPITER Size and Composition: Jupiter is the largest planet in our solar system, with a diameter of about 143,000 kilometers (89,000 miles). It is primarily composed of hydrogen and helium, similar to the composition of the Sun, but it lacks the critical mass required to trigger nuclear fusion and become a star. Great Red Spot: Jupiter is well-known for its iconic feature called the Great Red Spot. It is a persistent high-pressure storm system, appearing as a large reddish-colored oval on the planet's surface. The Great Red Spot is a centuries-old storm that is larger than Earth itself. SATURN Rings of Saturn: Saturn's iconic rings are composed of countless icy particles ranging in size from micrometers to several meters. These rings are made visible by the sunlight reflecting off the particles, creating a stunning and distinct feature. Cassini Mission: The Cassini spacecraft, launched in 1997, provided a wealth of information about Saturn and its moons. It orbited Saturn for over 13 years and captured breathtaking images of the planet, its rings, and its moons. The mission concluded in 2017 with a controlled descent into Saturn's atmosphere. Hexagonal Storm: Saturn's north pole is home to a unique atmospheric phenomenon known as the hexagonal storm. This massive, persistently swirling storm forms a hexagonal shape and has a central vortex. The exact cause of this peculiar weather pattern is still under investigation. COMETS Composition: Comets are composed of ice, rock, dust, and organic compounds. Their icy nucleus contains a mixture of water, frozen gases (such as carbon dioxide and methane), and various types of solid particles. Orbits: Comets have elongated orbits that can take them far from the Sun, often originating from the Kuiper Belt or the Oort Cloud. When a comet's orbit brings it closer to the Sun, the heat causes the ice to vaporize, creating a glowing coma and distinctive tails. Scientific Significance: Comets are of great scientific importance as they provide a window into the early solar system's formation. By studying comets, scientists can gain insights into the composition and processes that occurred during the formation of planets and other celestial bodies billions of years ago. Space missions have been launched to explore and gather data directly from comets, enhancing our understanding of these fascinating objects. URANUS Unique Tilt: Uranus is known for its extreme axial tilt, as it rotates on its side compared to other planets in the solar system. This tilt is believed to have resulted from a collision with a massive object early in its history, causing its axis to be tilted at an angle of about 98 degrees. Atmosphere: Uranus has a predominantly hydrogen and helium atmosphere, but it also contains traces of methane. This methane gives Uranus its distinctive blue-green color, as it absorbs red light and reflects blue and green light back into space. The atmosphere is characterized by high-speed winds, reaching speeds of up to 900 kilometers per hour (560 miles per hour). Moons and Rings: Uranus has 27 known moons, named after characters from the works of William Shakespeare and Alexander Pope. The five largest moons are Miranda, Ariel, Umbriel, Titania, and Oberon. Uranus also has a system of rings, although they are not as prominent as the rings of Saturn. The rings are relatively dark and composed of ice particles mixed with rocky material. NEPTUNE Position and Distance: Neptune is the eighth and farthest planet from the Sun in our solar system, located about 4.5 billion kilometers (2.8 billion miles) away from the Sun. It takes approximately 165 Earth years for Neptune to complete one orbit around the Sun. Composition and Atmosphere: Neptune is an ice giant planet composed mainly of hydrogen, helium, and ices such as water, methane, and ammonia. Its atmosphere contains a high proportion of methane, which gives it a striking blue color. The presence of methane absorbs red light and reflects blue light, resulting in its distinct appearance. Moons and Rings: Neptune has a system of rings and a collection of moons. The most notable moon is Triton, which is the seventh-largest moon in the solar system and the only large moon in the solar system to orbit in the opposite direction of its planet's rotation. Neptune has a total of 14 known moons, including Nereid, Proteus, and Larissa KUIPER BELT Location and Size: The Kuiper Belt is a vast region of the solar system located beyond Neptune's orbit, extending from about 30 to 55 astronomical units (AU) from the Sun. It is estimated to be around 20 times wider and 200 times more massive than the asteroid belt between Mars and Jupiter. Composition and Objects: The Kuiper Belt is primarily composed of small icy bodies, including dwarf planets, comets, and a multitude of smaller objects known as Kuiper Belt Objects (KBOs). The most famous KBO is Pluto, which was reclassified as a dwarf planet in 2006. The region contains remnants from the early solar system and is believed to provide valuable insights into its formation and evolution. PLUTO Dwarf Planet: Pluto was once considered the ninth planet in our solar system but was reclassified as a dwarf planet in 2006 by the International Astronomical Union (IAU). It is located in the Kuiper Belt, a region beyond Neptune's orbit. Characteristics: Pluto has a rocky core surrounded by a thin atmosphere primarily composed of nitrogen, with traces of methane and carbon monoxide. It has five known moons, the largest of which is Charon, and its surface is covered in frozen nitrogen, methane, and carbon monoxide. Pluto's orbit is highly elliptical, and it takes about 248 Earth years to complete one orbit around the Sun. Charon and Other Moons: Pluto has five known moons, with Charon being the largest and most well-known. Charon is so large relative to Pluto that they are sometimes considered a "binary system." The other moons of Pluto are Nix, Hydra, Kerberos, and Styx. OORT CLOUD Distant Region: The Oort Cloud is a hypothetical, vast, and mostly spherical region that is believed to exist in the outermost reaches of the solar system, far beyond the Kuiper Belt. It is thought to extend from about 2,000 to 200,000 astronomical units (AU) from the Sun. Comet Reservoir: The Oort Cloud is believed to be the source of long-period comets, which are comets with orbital periods greater than 200 years. These comets originate from the Oort Cloud and are occasionally gravitationally perturbed, sending them on highly elliptical orbits that bring them into the inner solar system. Icy Objects: The Oort Cloud is presumed to contain trillions of icy bodies, composed primarily of volatile compounds such as water, methane, ammonia, and carbon dioxide. These objects are remnants from the early formation of the solar system and are thought to be relatively undisturbed since their creation billions of years ago.

  • Kepler 452 System | SPACELIA

    The TRAPPIST-1 system is a planetary system with seven Earth-sized planets orbiting a red dwarf star, TRAPPIST-1, located about 40 light-years away. Three of these planets, TRAPPIST-1e, f, and g, are within the star's habitable zone, where temperatures could allow for liquid water on the surface. Map of the Kepler 452 planetary system. Kepler 452 The Kepler-452 planetary system, discovered by the Kepler Space Telescope, consists of a sun-like star, Kepler-452, and at least one exoplanet, Kepler-452b. Kepler-452b is a "super-Earth" type planet located within the star's habitable zone, meaning it could potentially have liquid water on its surface. Kepler-452 b

  • KEPLER-452b | SPACELIA

    Kepler-452b, often referred to as "Earth's cousin," is an exoplanet that was discovered by NASA's Kepler Space Telescope. It was announced as a significant discovery in July 2015. Here's a detailed explanation of Kepler-452b, including information about its characteristics, atmosphere, and the potential for extraterrestrial life KEPLER-452b Kepler-452b, often referred to as "Earth's cousin," is an exoplanet that was discovered by NASA's Kepler Space Telescope. It was announced as a significant discovery in July 2015. Here's a detailed explanation of Kepler-452b, including information about its characteristics, atmosphere, and the potential for extraterrestrial life 1. Characteristics of Kepler-452b: Size and Mass: Kepler-452b is considered a super-Earth, as it is larger than Earth, with an estimated radius about 1.6 times that of Earth. However, its exact mass is still uncertain, as it depends on its composition, which is not precisely known. Orbit: Kepler-452b orbits a star known as Kepler-452, which is very similar to our Sun in terms of both size and temperature. Its orbit around Kepler-452 takes approximately 385 days, making it roughly analogous to Earth's year. Distance from Star: Kepler-452b is located within the habitable zone of its parent star. The habitable zone, also known as the "Goldilocks zone," is the region around a star where conditions may be right for liquid water to exist on the planet's surface—a key factor for the potential development of life as we know it. Age: The host star Kepler-452 is older than our Sun, estimated to be around 6 billion years old, which could have allowed more time for life to potentially develop on Kepler-452b. 2. Atmosphere of Kepler-452b: The exact composition and characteristics of Kepler-452b's atmosphere are not currently known. The detection and analysis of exoplanet atmospheres are challenging tasks and often require advanced instruments like the James Webb Space Telescope (scheduled for launch) to provide more detailed information. The presence and composition of an atmosphere are critical factors in determining the potential habitability of an exoplanet. An atmosphere can help regulate temperature, protect against harmful radiation, and play a role in supporting life processes. 3. Potential for Extraterrestrial Life: Kepler-452b's location within the habitable zone of its star makes it an intriguing candidate for the potential existence of extraterrestrial life. The habitable zone represents the region where conditions might be suitable for liquid water, a fundamental ingredient for life as we know it, to exist on the planet's surface. However, the presence of liquid water alone does not guarantee the existence of life. Many other factors, such as the planet's atmosphere, geological activity, and the availability of essential chemical ingredients, would also influence its habitability. Detecting signs of life on Kepler-452b or any exoplanet is extremely challenging and would likely require advanced telescopes capable of analyzing the planet's atmosphere for biomarkers (e.g., oxygen and methane) or other potential signs of biological activity. Kepler-452b and Earth are both planets, but they have some significant differences, as well as similarities. Here's a comparison between the two: 1. Size and Mass: Earth: Earth is approximately 12,742 kilometers (7,918 miles) in diameter and has a mass of about 5.972 × 10^24 kilograms. Kepler-452b: Kepler-452b is estimated to be about 1.6 times the size (radius) of Earth, but its mass is not precisely known. It's considered a super-Earth. 2. Orbit and Parent Star: Earth: Earth orbits the Sun, a G-type main-sequence star (G2V), at an average distance of about 149.6 million kilometers (93 million miles). Kepler-452b: Kepler-452b orbits a G-type main-sequence star (G2V) known as Kepler-452, which is very similar to the Sun. Its orbital period is approximately 385 Earth days. 3. Habitability and Atmosphere: Earth: Earth has a diverse and life-sustaining atmosphere composed primarily of nitrogen (78%) and oxygen (21%), with trace amounts of other gases. It has liquid water on its surface and a stable climate, making it highly habitable. Kepler-452b: The exact composition of Kepler-452b's atmosphere is not known, and its habitability is still uncertain. It's located within the habitable zone of its star, indicating the potential for liquid water, but more information about its atmosphere is needed to assess its suitability for life. 4. Age: Earth: Earth is approximately 4.5 billion years old. Kepler-452b: The host star Kepler-452 is estimated to be about 6 billion years old, making it older than the Sun. This could have implications for the potential development of life on the planet. 5. Surface Conditions: Earth: Earth has a diverse range of surface conditions, including continents, oceans, and various climate zones. It supports a wide variety of life forms and ecosystems. Kepler-452b: The specific surface conditions of Kepler-452b, such as the presence of oceans or continents, are not known due to limited observational data. 6. Potential for Extraterrestrial Life: Earth: Earth is known to host a vast array of life, from microorganisms to complex multicellular organisms, including humans. Kepler-452b: Kepler-452b is considered a potentially habitable exoplanet due to its location within the habitable zone, but the presence of extraterrestrial life on the planet is purely speculative at this point. More research and observations are needed to assess its habitability and the potential for life. Other Articles......

    In the late 1990s, astronomers found evidence that the expansion of the universe was not slowing down due to gravity as expected. Instead, the expansion speed was increasing. Something had to be powering this accelerating universe and, in part due to its unknown nature, this “something” was called dark energy.

In the late 1990s, astronomers found evidence that the expansion of the universe was not slowing down due to gravity as expected. Instead, the expansion speed was increasing. Something had to be powering this accelerating universe and, in part due to its unknown nature, this “something” was called dark energy. Hubble plays an important role in verifying, characterizing and constraining dark energy. Both Hubble and ground-based observations measures a special type of stellar explosion, a white dwarf supernova, to measure accurate distances to galaxies. A galaxy located a billion light-years away provides a data point for the universe as it was a billion years ago. Meanwhile, as the universe expands, the light traveling to Earth from distant galaxies (and their supernovas) is stretched out to longer wavelengths — a phenomenon called cosmological redshift. The cosmological redshifts of galaxies at different distances provides a history of the expansion of the universe over time. However, only Hubble had the resolution to extend these observations to very distant galaxies. The discovery of supernova 1997ff, located about 10 billion light-years away, provided evidence for dark energy. About halfway into the universe’s history — several billion years ago — dark energy became dominant and the expansion accelerated. While ground-based studies had measured this accelerating period, Hubble’s observation of 1997ff stretched back to the decelerating part of the expansion. This shift between two different eras of the universe — a change from a decelerating universe to an accelerating universe — showed that dark energy exists. Hubble continued to explore the nature of dark energy with observations such as the Great Observatories Origins Deep Survey (GOODS), structured to help uncover distant supernovas. The 42 supernovas found by Hubble not only solidified the conclusions about dark energy, but also began to constrain some of its possible explanations. Later Hubble results identified how early in the universe dark energy began to influence the expansion as well as constrained the current expansion rate. The view that emerged was that dark energy was consistent with the slow, steady force of Einstein’s cosmological constant, a concept that the physicist had initially introduced into his equations to prevent his theoretical universe from collapsing, then later retracted when the expansion of the universe was discovered. But instead of holding the universe in a steady state, dark energy is pushing outward to expand the universe faster and faster. The discovery of dark energy was recognized by the Nobel Prize in Physics in 2011. Astronomers now know that there is much more to the universe than meets the eye. The luminous and non-luminous normal matter makes up about 4 percent of the total mass and energy density of the universe. Dark matter, which emits no light and cannot be directly observed, comprises another 24 percent of the total, while dark energy dominates with about 72 percent. Most of the universe is unknown and only indirectly detected. We can see its effects on galaxies and the expansion of the universe, but we have yet to identify the underlying source. That may seem unsettling, but to a scientist, it is exciting. There are more great mysteries to explore and solve! The universe is expanding, and that expansion stretches light traveling through space in a phenomenon known as cosmological redshift. The greater the redshift, the greater the distance the light has traveled. Within the Hubble Deep Field-North region, astronomers pinpointed a blaze of light from one of the farthest supernovas ever seen. In a close-up view of that region (left) a white arrow points to a faint elliptical, the home of the exploding SN 1997ff. The supernova itself (right) is distinguished by the white dot in the center. This diagram reveals changes in the rate of expansion since the universe's birth 15 billion years ago. The more shallow the curve, the faster the rate of expansion. The curve changes noticeably about 7.5 billion years ago, when objects in the universe began flying apart as a faster rate. Astronomers theorize that the faster expansion rate is due to a mysterious, dark force that is pulling galaxies apart. This image is a portion of the GOODS-North field. The field features approximately 15,000 galaxies, about 12,000 of which are forming stars. Hubble’s ultraviolet vision opened a new window on the evolving universe, tracking the birth of stars over the last 11 billion years back to the cosmos’ busiest star-forming period about 3 billion years after the big bang. Spiral galaxy NGC 3021 (background) was one of several hosts of Type Ia supernovae observed by astronomers to refine the measure of the universe's expansion rate, called the Hubble constant. Hubble made precise measurements of Cepheid variable stars in the galaxy, highlighted by green circles in the inset boxes. Other Articles......

  • Black Hole | SPACELIA

    A black hole is an extremely dense region in space where gravity is so strong that nothing, not even light, can escape its grasp. It forms when a massive star collapses, creating a point called a singularity surrounded by an event horizon, beyond which nothing can return. Black holes come in various sizes, including stellar-mass and supermassive black holes. Black Hole A black hole is an extremely dense region in space where gravity is so strong that nothing, not even light, can escape its grasp. It forms when a massive star collapses, creating a point called a singularity surrounded by an event horizon, beyond which nothing can return. Black holes come in various sizes, including stellar-mass and supermassive black holes. What is Black Hole and how Black Hole forms? Today we will talk about black holes, first let us know how black holes are formed, to keep a star in balance, its gravitational force pushes it inwards and the nuclear fusion taking place in its center pushes it outwards. And with the help of these two pushing forces, the star remains under control. But when the helium gas inside the star starts getting exhausted then the nuclear energy of the star gradually gets exhausted, then gradually the star becomes a red giant, at this time the fusion happening on the star which prevents the gravity from pushing it inside. The force is no longer there and due to gravity the star seems to shrink in on itself and a time comes when the center of the star cannot handle so much gas and a big explosion occurs which we call a supernova, and at the end of the supernova A black hole is formed in A black hole has so much mass that even light gets trapped in front of its gravity and it also absorbs light into itself. Black hole is the center of an infinite mass around which there is a ring like event horizon. Original image of Black hole in i.c.1, explanation of black hole formation i.c.2 i.c.1 Black Hole event horizon. i.c.1 Black Hole formation. Time travel using Black Hole? I hope you have understood what a black hole is and how it is formed. There are many more questions about black holes for which we do not have answers, what is inside a black hole?, where do things go inside a black hole?, does it have an alternative white hole?, do all these things come out of the white hole? Does it come?, Can a black hole take us to our past or make us travel through time? We have not been able to find the answer to this mystery. Suppose we have detected a black hole, yet the nearest black hole is also 1560 light years away from us! If we travel at the speed of light, it will be approximately 1560 years and we can travel in space at the speed of light. Couldn't even find any solution. So as of today it is not possible to reach a black hole. But what's the point in believing, so let's take time and even if we reach the black hole, there will be many more difficulties in front of us, which I will tell you later. You all must have seen the movie Interstellar, in which a planet is shown which is very close to the black hole and we all know that the black hole has infinite mass and its space-time curvature is also very high, meaning it is very close to the black hole. Even spending a little time is a lot of years according to Earth, it is shown in this movie that 1 hour spent on Miller's Planet is equal to 7 years on Earth. And we call this effect time dilation. But we have to go inside it, not around it, and if the black hole also pulls the light inside itself, then we will have to travel at a speed faster than the light, there is another twist in this, we will first go to the event horizon of the black hole where all the things It starts rotating around the black hole, if we can survive there then we can reach inside the black hole, but we do not even know what is inside the black hole. So if we cross all these things then we can go inside the black hole. Scientists speculate that a black hole may act like a worm hole, just like the one shown in Interstellar. If you also want such an article like Worm Hole, then subscribe to the website so that you get the notification of that article. Now you can understand how complex the black hole is and we have not been able to solve the entire mystery of the black hole yet. i.c.3 Black hole event horizon. i.c.4 Black hole curvature comparison i.c.5 Black hole time travel.

  • Hubble's Galaxy Discovery | SPACELIA

    Our Sun is just one of a vast number of stars within a galaxy called the Milky Way, which in turn is only one of the billions of galaxies in our universe. These massive cosmic neighborhoods, made up of stars, dust, and gas held together by gravity, come in a variety of sizes, from dwarf galaxies containing as few as 100 million stars to giant galaxies of more than a trillion stars. Galaxies like Whirlpool, Sombrero, Andromeda, M100, Roe Galaxy, Antennae Galaxy. Hubble's Galaxy Discoveries Our Sun is just one of a vast number of stars within a galaxy called the Milky Way, which in turn is only one of the billions of galaxies in our universe. These massive cosmic neighborhoods, made up of stars, dust, and gas held together by gravity, come in a variety of sizes, from dwarf galaxies containing as few as 100 million stars to giant galaxies of more than a trillion stars. Astronomers generally classify galaxies into three major categories: spiral – like our Milky Way – elliptical, and irregular. Astronomers quickly realized that Hubble had a flaw. Its mirror was slightly the wrong shape, causing the light that bounced off the center of the mirror to focus in a different place than light bouncing off the edge. This “spherical aberration,” about 1/50th the thickness of a sheet of paper, was corrected during the first servicing mission in 1993 with installation of the Corrective Optics Space Telescope Axial Replacement (COSTAR). The result was highresolution imaging as shown in the image of galaxy M100. Since then, all of Hubble’s instruments have had corrective optics built in, eventually making COSTAR unnecessary. It was removed from the telescope in 2009. Hubble was upgraded four more times with improved instruments. The inset image is from Servicing Mission 1 (STS-61, Space Shuttle Endeavor) which took place in December 1993. Astronauts installed COSTAR and replaced Wide-Field Planetary Camera 1 (WFPC1) with Wide-Field Planetary Camera 2 (WFPC2), the first instrument to have the correction built into its optics. The image shows astronauts replacing WFPC1 with WFPC2. Detailed note: The two images of the center of galaxy Messier 100 show WFPC1 and WFPC2 data and demonstrate how well Servicing Mission 1 corrected the mirror flaw. Hubble could now achieve its design specifications. The largest Hubble Space Telescope image ever assembled, this sweeping view of a portion of the Andromeda galaxy (M31) is the sharpest large composite image ever taken of our galactic neighbor. Though the galaxy is over 2 million light-years away, Hubble is powerful enough to resolve individual stars in a 61,000-light-year-long stretch of the galaxy. The Andromeda galaxy is only 2.5 million light-years from Earth, making it a much bigger target in the sky than the myriad galaxies Hubble routinely photographs that are billions of light-years away. The Hubble survey is assembled into a mosaic image using 7,398 exposures taken over 411 individual pointings. The data were taken with the Advanced Camera for Surveys. The lower left inset points out the numerous types of objects seen in the image. The lower right inset is a composite made from a series of ground observations that shows the entire M31 galaxy and the portion imaged by Hubble. This 91-million pixel mosaic of the Whirlpool Galaxy (M51) was released to celebrate Hubble’s 15th anniversary. Beyond the sheer beauty of the image, the details along the spiral arms follow the progression of star formation from dark dust clouds through pink star-forming regions to blue newborn star clusters. Some astronomers believe that the Whirlpool's arms are so prominent because of the effects of a close encounter with NGC 5195, the small, yellowish galaxy at the outermost tip of one of the Whirlpool's arm. The distance to M51 is 23 million light years (7 megaparsecs). This image of the Sombrero Galaxy is one of the first large mosaics produced from the Advanced Camera for Surveys instrument. Combining data from six pointings, the full resolution image contains over 70 million pixels. The Sombrero is cataloged as Messier 104 (M104). The galaxy's hallmark is a brilliant white, bulbous core encircled by the thick dust lanes comprising the spiral structure of the galaxy. As seen from Earth, the galaxy is tilted nearly edge-on. We view it from just six degrees north of its equatorial plane. This brilliant galaxy was named the Sombrero because of its resemblance to the broad rim and high-topped Mexican hat. Sombrero is 28 million light years (9 megaparsecs) away. These two spiral galaxies started to interact a few hundred million years ago, making the Antennae galaxies one of the nearest and youngest examples of a pair of colliding galaxies. Nearly half of the faint objects in the Antennae image are young clusters containing tens of thousands of stars. The orange blobs to the left and right of image center are the two cores of the original galaxies and consist mainly of old stars criss-crossed by filaments of dust, which appear brown in the image. The two galaxies are dotted with brilliant blue star-forming regions surrounded by glowing hydrogen gas, appearing in the image in pink. The image allows astronomers to better distinguish between the stars and super star clusters created in the collision of two spiral galaxies. The Antennae are 62 million light years (19 megaparsecs) away. Galaxy interactions are not always the grand collisions seen in the Antennae galaxies. These two interacting galaxies, called the Rose Galaxy or catalog name Arp 273, have produced less pronounced distortions in each others’ shape. The larger of the spiral galaxies, known as UGC 1810, has a disk that is tidally distorted into a rose-like shape by the gravitational tidal pull of the companion galaxy below it, known as UGC 1813. A swath of blue jewels across the top is the combined light from clusters of intensely bright and hot young blue stars. These massive stars glow fiercely in ultraviolet light. The smaller, nearly edge-on companion shows distinct signs of intense star formation at its nucleus, perhaps triggered by the encounter with the companion galaxy. Some called this picture a “rose” of galaxies, with the upper galaxy as the bloom, and the lower galaxy as the stem. The pair is 340 million light years (105 megaparsecs) away.

  • STAR VFTS102 | SPACELIA

    We present a spectroscopic analysis of an extremely rapidly rotating late O-type star, VFTS102, observed during a spectroscopic survey of 30 Doradus. VFTS102 has a projected rotational velocity larger than 500 km s−1 and probably as large as 600 km s−1; as such it would appear to be the most rapidly rotating massive star currently identified. Its radial velocity differs by 40 km s−1 from the mean for 30 Doradus, suggesting that it is a runaway. O-TYPE STAR VFTS102 We present a spectroscopic analysis of an extremely rapidly rotating late O-type star, VFTS102, observed during a spectroscopic survey of 30 Doradus. VFTS102 has a projected rotational velocity larger than 500 km s−1 and probably as large as 600 km s−1; as such it would appear to be the most rapidly rotating massive star currently identified. Its radial velocity differs by 40 km s−1 from the mean for 30 Doradus, suggesting that it is a runaway. By : P. Dufton et al 1. Introduction In recent years the importance of binarity in the evolution of massive stars has been increasingly recognised. This arises from most OB-type stars residing in multiple systems (Mason et al. 2009) and the significant changes to stellar properties that binarity can cause (see, for example, Podsiadlowski et al. 1992; Langer et al. 2008; Eldridge et al. 2011). Here we present a spectroscopic analysis of a rapidly rotating (veq sin i ∼ 600 km s−1) O-type star in the 30 Doradus region of the Large Magellanic Cloud (LMC). Designated VFTS102 (Evans et al. 2011, hereafter Paper I)1, the star is rotating more rapidly than any observed in recent large surveys (M artayan et al. 2006; Hunter et al. 2009) and may also be a runaway. It lies less than one arcminute from the X-ray pulsar, PSR J0537-6910, which is moving away from it. We suggest that VFTS102 might originally have been part of a binary system with the progenitor of the pulsar. 2. Observations Spectroscopy of VFTS102 was obtained as part of the VLT-FLAMES Tarantula Survey, covering the 3980-5050˚A region at a spectral resolving power of 7000 to 8500. Spectroscopy of the Hα region was also available, although this was not used in the quantitative analysis. Details of the observations and initial data reduction are available in Paper I. The spectra were normalised to selected continuum windows using a sigma-clipping rejection algorithm to exclude cosmic rays. No velocity shifts were observed between different epochs, although simulations (see, Sana et al. 2009) indicate that 30% of short period (less 1Aliases include: ST92 1-32; 2MASS J05373924-6909510 –3– than 10 days) and effectively all longer term binaries would not have been detected. We have therefore assumed VFTS102 to be single and the sigma-clipped merged spectrum displays a signal-to-noise ratio of approximately 130 and 60 for the 4000-4500 and 4500-5000˚A regions respectively. An O9: Vnnne spectral classification was obtained by smoothing and rebinning the spectrum to an effective resolving power of 4000 and comparing with standards compiled for the Tarantula Survey (Sana et al. in preparation). The principle uncertainties arise from the extremely large rotational broadening and significant nebular contamination of the He I lines, with the two suffixes indicating extreme line broadening (‘nnn’) and an emission-line s tar (‘e’). 3. Analysis 3.1. Projected rotational velocity The large rotational broadening of the spectral features makes reliable measurements of the projected rotational velocity, veq sin i , difficult. We have used a Fourier Transform (FT) approach as discussed by Sim´on-D´ıaz & Herrero (2007), supplemented by fitting rotational broadened profiles (PF) to the observed spectral features. The Balmer lines have significant nebular emission and hence the weaker helium spectra were utilized, as illustrated in Fig. 1. The He I line at 4471˚A, although well observed, also showed significant nebular emission and was not analysed. By contrast the line at 4026˚A showed no evidence of emission and yielded a plausible minimum in the Fourier Transform for a veq sin i of 560 km s−1. The PF methodology leads to a slightly higher estimate (580 km s−1). The He I lines at 4143 and 4387˚A were observed although they are relatively weak. They and the line at 4026˚A were converted into velocity space, merged and analysed. The two methodologies yielded effectively identical estimates of 640 km s−1; a similar procedure was undertaken for the He II lines at 4200 and 4541˚A yielding 540 km s−1 (FT) and 510 km s−1 (PF). The He II line at 4686˚A was found to be sensitive to the normalisation with a veq sin i of ∼560 km s−1 being estimated. The individual results should be treated with caution but overall they imply that this star is rotating near to its critical velocity, with the mean value for the FT estimates being 580 km s−1. As discussed by Townsend et al. (2004), projected rotational velocities may be underestimated at these large velocities. For a B0 star rotating at 95% of the critical velocity, this underestimation will be approximately 10%. Hence our best estimate for the projected rotational velocity is ∼600 km s−1. A lower limit of 500 km s−1 has been adopted, whilst the upper value will be constrained by the critical velocity of approximately 700 km s−1 from the models of Brott et al. (2011). This estimate is significantly higher than those (! 370 km s−1) found by Martayan et al. (2006) and Hunter et al. (2009) in their LMC B-type stellar samples. It is also larger than any of the preliminary estimates (!450 km s−1) for ∼ 270 B-type stars in the Tarantula survey, although other rapidly rotating O-type stars have been identified. As such it would appear to have the highest projected rotational velocity estimate of any massive star yet analysed. 3.2. Radial velocity Radial velocities were measured by cross-correlating spectral features against a theoretical template spectrum taken from a grid calculated using the code TLUSTY Hubeny (1988) – see Dufton et al. (20 05) for details. Five spectral regions were considered, viz. Hδ and Hγ (with the cores excluded); He I at 4026˚A; 4630-4700˚A with strong multiplets due to C III and O II and an He II line; 4000-4500˚A (with nebular emission being excluded). The measurements are in excellent agreement with a mean value of 228±12 km s−1; if the error distribution is normally distributed the uncertainty in this mean value would be 6 km s−1. From a study of ∼180 presumably single O-type stars in the Tarantula survey Sana et al. (in preparation) find a mean velocity of 271 km s−1 with a standard deviation of 10 km s−1. Preliminary analysis of the B-type stars in the same survey has yielded 270±17 km s−1. VFTS102 lies more than two standard deviations away from these results, implying that it might be a runaway. 3.3. Atmospheric parameters While the equatorial regions of VFTS102 will have a lower gravity than the poles (because of centrifugal forces), and hence a lower temperature (because of von Zeipel gravity darkening), we first characterise the spectrum by comparison with those generated with spatially homogeneous models, convol ved with a simple rotational-broadening function. We have used both our TLUSTY grid and FASTWIND calculations (Puls et al. 2005), adopting an LMC chemical composition. For the former, the strength of the He II spectrum implies an effective temperature (Teff) of ∼32500–35000 K, whilst the wings of the Balmer lines lead to a surface-gravity estimate of ∼3.5 dex (cgs). For the latter after allowing for wind effects, the corresponding parameters are 37000 K and 3.7 dex. The helium spectra are consistent with a solar abundance but with the observational and theoretical uncertainties we cannot rule out an enhancement. Given its projected equatorial rotation velocity, VFTS102 is almost certainly viewed at sin i ∼ 1. Hence the relatively cool, low-gravity equatorial regions will contribute significantly to the spectrum. Although their surface flux is lower than for the brighter poles, the analyses discussed above may underestimate the global effective temperature and gravity. However, the rotating-star models discussed below suggest that the effects are not very large. We therefore adopt global estimates for the effective temperature of 36000 K and 3.6 dex but note that the polar gravity could be as large as 4.0 dex. Varying the global parameters by the error estimates listed in Table 1 leads to significantly poorer matches between observation and the standard models, but, given the caveats discussed above, those errors should still be treated with caution. For near critical rotational velocities, the stellar mass can be estimated. Howarth & Smith (2001) show that the stellar mass can be written in terms of ω/ωc 2, veq and the polar radius. Assuming that sin i ∼ 1 and adopting the critical velocities from our single star models, we can estimate the first two quantities. Additionally for any given value of ω/ωc, the polar radius can be inferred from the absolute visual magnitude and the unreddened (B-V). The former can be estimated from the luminosity (see Sect. 3.4) and the latter from our effective temperature estimate and the LMC broad-band intensities calculated by Howarth (2011). We find M " 20 M# for veq ∼ 600 km s−1 and Teff ! 38000 K. Only by adopting a smaller value for veq can we push the mass limit down, but even with veq ∼ 500 km s−1 the mass must exceed ∼17M#. 3.4. Luminosity From extant photometry (see Paper I), the (B-V) colour of VFTS102 is 0.35, implying an E(B-V) of 0.6 using colours calculated from our TLUSTY grid. Adopting a standard reddening law leads to a lo garithmic luminosity (in solar units) of 5.0 dex, with an E(B-V) error of ±0.1 corresponding to an uncertainty of ±0.1 dex. However there are other possible sources of error, for example deviations from a standard reddening law and hence we have adopted a larger random error estimate of ±0.2 dex. 2The ratio of the equatorial angular velocity to that at which the centrifugal acceleration equals the gravitational acceleration. As VFTS102 is an Oe-type star, its intrinsic colours may be redder than predicted by our TLUSTY grid and indeed an infrared excess is found from published (de-reddened) 2MASS photometry. Inspection of a K-band VISTA image shows no evidence of contamination by nearby sources. Further evidence for circumstellar material is found in the strong Hα emission, which is double peaked as is the nearby He I line at 6678˚A, which supports our adoption of a sin i ∼ 1. Additionally there are weak double-peaked Fe II emission features (e.g. at 4233˚A), consistent with an Oe-type classification. Unfortunately our photometry and spectroscopy are not contemporaneous but if VFTS102 was in a high state when the optical photometry was taken, we may have overestimated the luminosity of the central star (see de Wit et al. 2006, for colour and magnitude variations of Be stars). 4. Past and future evolution Stellar evolution calculations for both single and binary stars are available in the literature (see Maeder & Meynet 2011). For very fast rotation, they suggest that rotational mixing is so efficient that stars may evolve quasi-chemically homogeneously (Maeder 1987; Woosley & Heger 2006; Cantiello et al. 2007 ; de Mink et al. 2009; Brott et al. 2011). However, with different physical assumptions, models do not evolve chemically homogeneously even for the fastest rotation rates (Cantiello et al. 2007; Ekstr¨om et al. 2008). 4.1. Single star evolution Fig. 2 illustrates evolutionary tracks for LMC single stars calculated using the methodology of Brott et al. (2011) for an initial equatorial rotational velocity of 600 km s−1, together with that for a more slowly rotating model. The former are evolving chemically homogeneously whilst the latter follows a ‘normal’ evolutionary path. Ekstr¨om et al. (2008) calculated models for a range of metallicities and masses between 3 and 60 M# but found that the stars followed normal evolutionary paths even for near critical rotational velocities. The estimated parameters of VFTS102 are consistent with our tracks for initial masses of ∼20-30 M#. Our models show a relatively rapid increase in the surface helium abundance due to their homogeneous evolution. For example the 25 M# model shows an enrichment of a factor of two after approximately 4 million years and when the effective temperature has increased to approximately 39000 K. By contrast the models of Ekstr¨om et al. (2008) show no significant helium abundance implying that an accurate helium abundance estimate for VFTS102 would help constrain the physical assumptions. –7– 4.2. Binary star evolution Below, we first discuss the environment of VFTS102 and then consider a possible evolutionary scen a rio. 4.2.1. A pulsar near VFTS102 VFTS102 lies in a complex environment near the open cluster NGC 2060. In particular it lies close to a young X-ray pulsar PSR J0537-6910 (Marshall et al. 1998) and the Crab-like supernova remnant B0538-691 (Micelotta et al. 2009). VFTS102 has an angular separation of approximately 0.8 arcminutes from PSR J0537-6910 implying a spatial separation (in the plane of the sky) of approximately 12 pc. The X-ray emission consists of a pulsed localised component and a more spatially diffuse component, with the latter providing the majority of the energy. The diffuse component was identified in ROSAT and ASCA observations by Wang & Gotthelf (1998a) and interpreted as coming from ram-pressure-confined material with the X-ray pulsar being identified soon afterwards by Marshall et al. (1998). Wang & Gotthelf (1998b) analysed ROSAT HRI observations and suggested that the emission could come from the remnants of a bow shock if the pulsar was moving with a velocity of ∼1000 km s−1. Wang et al. (2001) subsequently analysed higher spatial resolution CHANDRA observations, which clearly delineated this emission and implied that the pulsar was moving away from VFTS102. Fig. 3 superimposes these emission contours onto an HST optical image with VFTS102 being near the tail of these contours. As discussed by Wang et al. (2001) the spatial distribution of the diffuse X-ray emission and the SNR optical emission are well correlated. Differences probably arise from a foreground dark cloud and photoionization and mechanical energy input from the nearby open cluster. Timing measurements imply that the pulsar has a characteristic age of 5000 years (Marshall et al. 1998), consistent with the age estimate of Wang & Gotthelf (1998b) from analysis of X-ray emission. Spyrou & Stergioulas (2002) discuss the estimation of ages from spin rates and find the results to be sensitive to both the breaking index and the composition of the pulsar core. Indeed phase connected braking index measurements for young pulsars (see Zhang et al. 2001, and references therein) yield breaking indices lower than the n=3 normally adopted with corresponding increases in the characteristic ages. Additionally, Chu et al. (1992) found an age of approximately 24000 years from the kinematics of the supernova remnant. Adopting an age of 5000 years would imply that if these objects had been part of a binary system, their relative velocity (vs ) in the plane of the sky would be approximately 2500 km s−1. Increasing this age to 24000 years would then imply vs ∼ 500 km s−1. These values although large are consistent with a pulsar velocity of 1000 km s−1 in the model of Wang & Gotthelf (1998b) and of ∼600 km s−1 from the separation of the diffuse X-ray and radio emission (Wang et al. 2001). Additionally Hobbs et al. (2005) found a mean space velocity of approximately 400 km s−1 for a sample of young pulsars with velocities as high as 1600 km s−1. From the theoretical point of view, Stone (1982) found supernova kick velocities normally in excess of 300 km s−1, while more recently Eldridge et al. (2011) estimated kickvelocities for a single neutron star of more than 1000 km s−1with a mean value of ∼500 km s−1. 4.2.2. A binary evolution scenario for VFTS1 02 While the fast rotation of VFTS102 might be the result of the star formation process, it could also have arisen from spin-up due to mass transfer in a binary system (Packet 1981). A subsequent superno va explosion of the donor star could then lead to an anomalous radial velocity for VFTS102 (Blaauw 1961; Stone 1982). The nearby pulsar and supernova remnant make this an attractive scenario. Of course, we cannot eliminate other possible scenarios, e.g. dynamical ejection from a cluster (see Gvaramadze & Gualandris 2011) but it is unclear whether these could produce the very large rotational velocity of VFTS102. Cantiello et al. (2007) have modelled a binary system with initial masses of 15 and 16 M# adopting SMC metallicity. After mass transfer the primary exploded as a type Ib/c supernova. At that stage the secondary has a mass of approximately 21 M#, a rotational velocity close to critical and a logarithmic luminosity of approximately 4.9 dex (see Fig. 2 for its subsequent evolution). These properties closely match the estimates for VFTS102 summarized in Table 1. Based on grids of detailed binary evolutionary models (Wellstein et al. 2001; de Mink et al. 2007), the initial masses of the two components of such a binary system should be comparable, with M2/M1 " 0.7. If the initial mass of the secondary was in the range of 14-18 M#, that of the primary would need to be smaller than about 25 M#. This agrees with the estimated initial mass of the supernova progenitor based on the kinematics of the supernova remnant (Micelotta et al. 2009). In this scenario, it takes the primary star about 11 Myr to evolve to the supernova stage. While the most massive stars in 30 Doradus have ages of a few million years (Walborn et al. 1999), there is also evidence for different massive stellar populations with ages ranging up to about 10 Myr (Walborn & Blades 1997). Recently, De Marchi et al. (2011) have undertaken an extensive study of lower mass (!4 M#) main sequence and pre-main sequence stars in 30 Doradus. They obtain a median age of 12 Myr with ages of up 30 Myr. Hence it would appear possible that the putative binary system formed in the vicinity of 30 Doradus approximately 10 Myr ago and underwent an evolutionary history similar to that modelled by Cantiello et al. (2007). Proper motion information would be extremely valuable to further test this hypothesis. PSR J0537-6910 has not been definitely identified in other wavelength regions. Mignani et al. (2005) using ACS imaging from the Hubble Space telescope found two plausible identifications that would imply an optical luminosity similar to the Crab-like pulsars. A radio survey by Manchester et al. (2006) only yielded an upper limit to its luminosity consistent with other millisecond pulsars. However estimates for both components may be obtained from the HST proper motion study (Programme: 12499; PI: D.J. Lennon) that is currently underway. 4.3. Evolutionary future Irrespective of the origin of VFTS102, it is interesting to consider its likely fate. Stellar evolutionary models of rapidly rotating stars have recently been generated by Woosley & Heger (2006) and Yoon et al. (2006). The latter consider the fate of objects with rotational velocities up to the critical val ue (vc ). The evolution is shown to depend not only on initial mass and rotational velocity but also on the metallicity. In particular GRBs are predicted to occur only at sub-solar metallicities. Based on our single star models, VFTS102 has a rotational velocity above ∼ 0.8vc and is thus expected to evolve quasi-chemically homogeneously. While Yoon et al. (2006) and Woosley & Heger (2006) estimate the metallicity threshold for GRB formation from chemically homogeneous evolution to be somewhat below the LMC metallicity, the latter note its sensitivity to the mass loss rate (Vink & de Koter 2005). Indeed all our most rapidly rotating 20 − 30 M# models are evolving chemically homogeneously throughout core hydrogen burning (Fig. 2), a prerequisite to qualify for a GRB progenitor. In any case, within the context of homogeneous evolution VFTS102 is expected to form a rapidly rotating black hole, and a Type Ic hypernova. This conjecture remains the same within the binary scenario of Cantiello et al. (2007). Assuming a space velocity of 40 km s−1 for VFTS102 (compatible with its anomalous radial velocity), our evolutionary models imply that VFTS102 will travel ∼300-400 pc before ending its life. This is consistent with the finding of Hammer et al. (2006) that the locations of three nearby GRBs were found several hundred parsecs away from their most likely progenitor birth locations (see, however, Margutti et al. 2007; Wiersema et al. 2007; Han et al. 2010). 5. Conclusions VFTS102 has a projected rotational velocity far higher than those found in previous surveys of massive stars in the LMC, and indeed it would appear to qualify as the most rapidly rotating massive star yet identified. With a luminosity of 105 L# we estimate its current mass to be approximately 25 M#. Its extreme rotation, peculiar radial velocity, proximity to the X-ray pulsar PSR J0537-6910 and to a superno va re mnant suggest that the star is the result of binary interaction. It is proposed that VFTS102 and the pulsar originated in a binary system with mass transfer spinning-up VFTS102 and the supernova explosion imparting radial velocity kicks to both components. If evolving chemically homogeneously, as suggested by recent models, VFTS102 could become a GRB or hypernova at the end of its life. Additionally it may provide a critical test case for chemically homogeneous evolution.

You may have seen the movie Interstellar where a man controls the fourth diamentio from the future and how our present is connected to our past, this basic concept is what I call the concept of Multiness of Thoughts. this concept is also connected with quantum theories, because this theory also say that all thigs which we see is create with our thoughts and after we see it's die immediately. An idea that forces us to think, what you are thinking now or what is happening to you is dependent on your footing, but how? What if you go ahead and get a good job, but you don't study? So you may not have sat on that achievement. Just like in the interstellar movie, your future is writing the present to you, the result of what you are doing now will be found in the future, so it is you who controls you from the future in the present. And against this, even if you connect the concept to the deje wan effect, you will get today's result, if future is actual then present, not actually, but yes it can be said that future is as equivalent as our present thoughts or our present situation right. And this universe is also a part of our concept, science su? Science is a medium to show our thoughts and our ability, so what is not like science? Not actually but science is a loop made up of our thoughts and just a thought? Is there a medium we use to present our skills? And all this is a multiplicity of ideas. It is human nature that if you think about something, then you walk in the light of that thing and your thoughts start to create that thing. So everything is just an illusion. We are a part of this universe, so whatever theories we have are the thoughts of our mind which we want to make true by any means. You must have experienced that sometimes when you go into deep thoughts, that thought seems true to you in real life too and this also happens with our dreams, then everything is fine, it is just an illusion of our thoughts and brain.

  • Proxima Centauri b | SPACELIA

    Proxima Centauri b is an exoplanet that orbits the red dwarf star Proxima Centauri, which is the closest known star to our Sun. Here's a detailed explanation of Proxima Centauri b, including information about its characteristics, atmosphere, and the search for extraterrestrial life or aliens Proxima Centauri b Proxima Centauri b is an exoplanet that orbits the red dwarf star Proxima Centauri, which is the closest known star to our Sun. Here's a detailed explanation of Proxima Centauri b, including information about its characteristics, atmosphere, and the search for extraterrestrial life or aliens 1. Characteristics of Proxima Centauri b: Size: Proxima Centauri b is classified as an exoplanet with a mass roughly similar to Earth's, making it about 1.3 times the mass of our planet. This places it in the category of terrestrial exoplanets, similar to Earth and Venus. Orbit: Proxima Centauri b orbits its host star, Proxima Centauri, at a very close distance, approximately 0.05 astronomical units (AU), or about 7.5 million kilometers (4.7 million miles). It completes an orbit in just around 11.2 Earth days. Habitability: Proxima Centauri b is located within the habitable zone (Goldilocks zone) of its star. This means it is in the region where conditions for liquid water to exist on the surface are possible, a key factor for potential habitability. 2. Atmosphere of Proxima Centauri b: Information about the specific composition and characteristics of Proxima Centauri b's atmosphere is not currently known. Detecting and analyzing the atmospheres of exoplanets, especially those as distant as Proxima Centauri b, is a challenging task and often requires advanced telescopes and instruments. 3. The Search for Extraterrestrial Life or Aliens: Proxima Centauri b has generated significant interest in the search for extraterrestrial life due to its proximity to Earth and its location within the habitable zone. Scientists and astronomers are particularly interested in studying exoplanets like Proxima Centauri b because they could offer insights into the potential for life beyond our solar system. The search for extraterrestrial life extends beyond Proxima Centauri b and includes the study of other exoplanets both within and outside the habitable zone. Key aspects of this search involve looking for signs of habitability and biomarkers, such as the presence of water, oxygen, and methane, in exoplanet atmospheres. The discovery of life, if it exists, on Proxima Centauri b or any other exoplanet would be a profound scientific breakthrough and could have far-reaching implications for our understanding of life's prevalence in the universe. It's important to note that as of my last knowledge update in September 2021, there is no definitive evidence of extraterrestrial life, and the search continues to be an active and ongoing scientific endeavor. Future missions and advanced technology, such as the James Webb Space Telescope, are expected to provide more data and insights into the atmospheres and potential habitability of exoplanets like Proxima Centauri b. Comparison with Earth Proxima Centauri b and Earth are both planets, but they have significant differences in terms of their characteristics, orbits, and potential habitability. Here's a comparison between the two: 1. Size and Mass: Earth: Earth is approximately 12,742 kilometers (7,918 miles) in diameter and has a mass of about 5.972 × 10^24 kilograms, making it a terrestrial planet with a solid surface. Proxima Centauri b: Proxima Centauri b is classified as an exoplanet, and its size and mass are roughly similar to Earth's, with a mass approximately 1.3 times that of Earth. This places it in the category of terrestrial exoplanets. 2. Parent Star and Orbit: Earth: Earth orbits the Sun, a G-type main-sequence star (G2V), at an average distance of about 149.6 million kilometers (93 million miles). It takes approximately 365.25 days to complete one orbit. Proxima Centauri b: Proxima Centauri b orbits a red dwarf star known as Proxima Centauri, which is cooler and smaller than the Sun. Its orbital distance is very close to its parent star, about 0.05 astronomical units, which is much closer than Earth's distance from the Sun. Proxima Centauri b completes an orbit in approximately 11.2 Earth days. 3. Habitability and Atmosphere: Earth: Earth is known for its diverse and life-sustaining atmosphere composed primarily of nitrogen (about 78%) and oxygen (about 21%), with trace amounts of other gases. It has liquid water on its surface, a stable climate, and a variety of ecosystems that support a wide range of life forms. Proxima Centauri b: Information about the specific composition and characteristics of Proxima Centauri b's atmosphere is not currently known. Detecting and analyzing exoplanet atmospheres, especially those as distant as Proxima Centauri b, is challenging and requires advanced telescopes and instruments. 4. Potential for Extraterrestrial Life: Earth: Earth is the only known planet to host a wide variety of life forms, from microorganisms to complex multicellular organisms, including humans. Proxima Centauri b: Proxima Centauri b is located within the habitable zone of its star, which means it could have conditions suitable for liquid water to exist on its surface. However, the presence of life on Proxima Centauri b is purely speculative at this point, and more research is needed to assess its habitability and the potential for extraterrestrial life.

  • Worm Hole | SPACELIA

    Worm Holes are one of the mysterious phenomenon in this Universe, It has the ability to bend the space time and let you to travel through Space and Time in a shorter period, Help of this phenomenon we could travel through galaxies that seems impossible right now. Worm Hole Let's begin the curvature of worm hole What is a worm hole?, how are worm holes formed?, and what is the function of a worm hole?, I will tell you all this in this article today, so first let's talk about what a worm hole is, how these worm holes are made and How it works, so worm hole connects two different places in space, just like a bridge, so that we can cover long distances in a short time, as you see in the image below, worm hole space. It bends like this and we can show it as a circle and a circle is a sphere in 3D, so the worm hole is also like a sphere. By traveling in this, you can bridge the distance between two places in a very short time, but a big question is that how are worm holes formed? We have heard about black holes that they are formed after supernova, but worm holes are We do not know how they are formed, worm holes are not a natural phenomenon, we have to create them artificially. But till date we have not succeeded in creating such a big worm hole, we have definitely done this test on a very small level but it is not enough for a human being, so only some advanced civilization can do this in the future. You are controlling us and they can create a worm hole just like the interstellar movie.

  • Zombie Planets | SPACELIA

    Zombie planets, also known as "pulsar planets" or "planets around pulsars," are a fascinating and relatively rare astronomical phenomenon Zombie Planets Zombie planets, also known as "pulsar planets" or "planets around pulsars," are a fascinating and relatively rare astronomical phenomenon Zombie Planets Zombie planets, also known as "pulsar planets" or "planets around pulsars," are a fascinating and relatively rare astronomical phenomenon. Here's a more detailed description and some interesting facts about zombie planets: Description: Zombie planets are exoplanets that survive the catastrophic death of their parent stars and continue to exist in orbit around a highly dense remnant called a pulsar. Pulsars are rapidly rotating neutron stars formed after massive stars undergo a supernova explosion. These pulsars emit intense beams of radiation from their poles, resembling lighthouse beams, due to their rapid rotation. If a planet is close enough to the pulsar but outside its destructive beam, it can potentially survive as a "zombie planet." Facts: Host Star Demise: Zombie planets are the remnants of planetary systems that were once part of a massive star. When the star runs out of nuclear fuel, it undergoes a supernova, releasing an enormous amount of energy, and leaving behind a collapsed core—a neutron star or pulsar. Extreme Conditions: Zombie planets are exposed to harsh conditions. They are incredibly cold and dark since they no longer receive any energy from their deceased parent star. Instead, they rely on the faint radiation and residual heat from the pulsar. Radioactive Environment: Pulsars emit powerful radiation, including X-rays and gamma rays, due to their rapid rotation and intense magnetic fields. Zombie planets within the pulsar's vicinity experience extreme radiation, making them inhospitable to life as we know it. Detection Challenges: Detecting zombie planets is challenging due to their remote and faint nature. Astronomers have to use advanced techniques, such as pulsar timing and indirect methods, to infer the presence of these planets. Potential Habitability: While the surface of zombie planets is inhospitable, there is speculation that subsurface regions or oceans shielded from radiation might harbor conditions suitable for life to exist. Candidate PSR B1257+12: One of the first and best-studied examples of a pulsar with planets is PSR B1257+12, located about 980 light-years away in the constellation Virgo. It has three known planets. Formation Theories: Zombie planets can potentially form from debris disks or leftover material around the pulsar after the supernova event. Another possibility is the capture of planets from other star systems. Interaction with Pulsar: The presence of a planet can influence the pulsar's rotational dynamics. The planet's gravitational pull causes slight variations in the pulsar's signal, enabling scientists to indirectly detect their presence. Astrophysical Curiosities: Zombie planets are intriguing astrophysical curiosities that expand our understanding of planetary systems, stellar evolution, and the complex dynamics in extreme environments. Future Exploration: As technology and observational capabilities improve, astronomers hope to discover more zombie planets and gain insights into their properties, helping us unravel the mysteries of these captivating celestial objects. Zombie planets represent a fascinating intersection of stellar remnants and planetary systems, offering a glimpse into the resilience of planets surviving extreme events in the universe. Further research and discoveries in this field may shed more light on these mysterious worlds. Other Articles......

  • Hubble's Deep Field | SPACELIA

    The Hubble Space Telescope has made over 1.5 million observations since its launch in 1990, capturing stunning subjects such as the Eagle Nebula and producing data that has been  featured in almost 18,000 scientific articles. But no image has revolutionized the way we understand the universe as much as the Hubble Deep Field. Hubble's Deep Field The Hubble Space Telescope has made over 1.5 million observations since its launch in 1990, capturing stunning subjects such as the Eagle Nebula and producing data that has been featured in almost 18,000 scientific articles. But no image has revolutionized the way we understand the universe as much as the Hubble Deep Field . A Core Sample of the Universe The Hubble Deep Field image holds 342 separate exposures taken between December 18 and 28, 1995. The picture we see was assembled from blue, red, and infrared light. The combination of these images allows astronomers to infer the distance, age, and composition of the galaxies photographed. Bluer objects, for example, contain young stars or could be relatively close. Redder objects contain older stars or could be farther away. Most of the galaxies are so faint ― four billion times fainter than the human eye can see ― that they had never been observed before, even by the largest telescopes. “As the images have come up on our screens, we have not been able to keep from wondering if we might somehow be seeing our own origins in all of this,” Williams said at the time. “These past 10 days have been an unbelievable experience.” The “deep” in Hubble Deep Field refers to the telescope’s ability to look at some of these far, faint objects. Looking at far-away objects in space is like seeing back in time. Light moves at tremendous speed, but it still takes time to travel across the vastness of space. Even the light from our own Sun needs eight minutes and 20 seconds to reach Earth, so when we look at the Sun, we see it as it was a little more than eight minutes earlier. The farther away the object, the younger it appears in Hubble’s gaze. The Deep Field was like a core sample of space, showing galaxies at different and earlier stages of development the deeper they appeared in the image. Researchers from the State University of New York at Stony Brook analyzed the photo and chose several dozen candidates that could be more distant than any galaxies seen up to that point. They identified the galaxies based on their color, because more distant galaxies appear redder as the light reaches us. This happens because the light stretches as it travels through the universe, transforming into infrared wavelengths, which are redder. A 1998 follow-up infrared image taken with Hubble’s Near Infrared Camera and Multi-Object Spectrometer discovered galaxies believed to be over 12 billion light-years away, even farther than those seen in the Hubble Deep Field. Hubble Deep Field South After the success of the original Hubble Deep Field, astronomers sought new ways to increase our understanding of the universe. Since it would take 900,000 years for astronomers to observe the whole sky, they knew they would have to rely on more samples like the Hubble Deep Field to infer what the entire universe looks like. The Hubble Deep Field South focused on a region in the constellation Tucana, near the south celestial pole, and doubled the number of distant galaxies available to astronomers. Williams and a team of 50 astronomers and technicians at the Institute and at Goddard Space Flight Center in Greenbelt, Maryland, carried out the 10-day-long observation in October 1998. Hubble Ultra Deep Field In 2004, Hubble captured a million-second-long exposure that contained 10,000 galaxies. This new image, the Hubble Ultra Deep Field, observed the first galaxies to emerge from the “dark ages,” a time just after the Big Bang. A servicing mission in 2002 had installed a new camera, called the Advanced Camera for Surveys. That camera had twice the field of view and a higher sensitivity than WFPC2, the camera that captured the original Deep Field. The final Ultra Deep Field photo is actually combined from an ACS image and an image from Hubble’s Near-Infrared Camera and Multi-object Spectrometer. “Hubble takes us to within a stone’s throw of the Big Bang itself,” said Massimo Stiavelli, an instrument scientist for Hubble at the Space Telescope Science Institute. From ground-based telescopes, the location of the Ultra Deep Field in the constellation Fornax ― right below the constellation Orion ― looked mostly empty, much like the other Deep Field locations, allowing for more distant observations to take place. The Ultra Deep Field image contained several odd galaxies, such as one shaped like a toothpick and another shaped like a bracelet link. Such galaxies come from a more chaotic time before the development of structured galaxies like the Milky Way. Ultra Deep Field data also taught astronomers that black holes at the center of galaxies likely grew over time, that large galaxies build up gradually as others merge and collide, and that some of the earliest galaxies were much smaller than our current Milky Way. Hubble Ultra Deep Field-Infrared In 2009, Hubble captured near-infrared light wavelengths in the same region as the Ultra Deep Field, revealing galaxies formed just 600 million years after the Big Bang. The light from one object, called UDFj-39546284, traveled 13.2 billion light-years to reach Earth. It’s a compact galaxy made up of blue stars, and astronomers found that the rate of star formation grew by a factor of 10 in just over 200 million years ― that may sound like a long time to us, but it’s tiny for the universe. Hubble eXtreme Deep Field In 2012, Hubble took it to the extreme. Astronomers combined 10 years of photographs taken of a region in the center of the original Ultra Deep Field. Even with its smaller view, the eXtreme Deep Field still showed 5,500 galaxies. The faintest galaxies visible in this image are one ten-billionth of what the human eye can see, and most of the galaxies shown are from when they were young and small, often colliding and merging together. Ultra Deep Field 2012 After observations made over six weeks in August and September 2012, a team of astronomers discovered a population of seven primitive galaxies formed when the universe was just 3% of its present age. The observations supported the idea that galaxies may have provided enough energy to reheat the universe after the Big Bang. Frontier Fields NASA’s Great Observatories ― Hubble, Spitzer, and Chandra ― teamed up in 2013 for the Frontier Fields, a bold multi-year campaign to provide critical data to aid investigations of dark matter and how galaxies change over time, among others. Abell 370 is a cluster with several hundred galaxies at its core. It was one of the first clusters where astronomers observed gravitational lensing and part of the Frontier Fields project. Credits: NASA, ESA, R. Bouwens and G. Illingworth (University of California, Santa Cruz) The campaign provided 12 new deep field images, and astronomers were able to detect galaxies 100 times fainter than those they observed in the Hubble Ultra Deep Field. Focusing on high-redshift galaxies and gravitational lensing, or the natural distortion of light from massive galaxy clusters, the team worked to detect galaxies too faint to be seen by Hubble alone. Such an undertaking propelled our understanding of the universe in ways that could only be achieved with all the Great Observatories working together. The campaign ended in 2017, and now astronomers can use the dataset to continue exploring the early universe. Not only did the Hubble Deep Field change how we understand the universe, it also changed how we share findings. “This coming together of the community to generate a shared, nonproprietary dataset was essentially unprecedented but has since become the model for the majority of large astronomical projects,” wrote University of Washington astronomer Julianne Dalcanton. “This new mode of operating has democratized astronomy.” Hubble’s data was compiled for the Legacy Field, a combination of nearly 7,500 Hubble exposures. It represents 16 years of observations, 265,000 galaxies, and 13.3 billion years, making it the largest collection of galaxies documented by Hubble. The role of exploring the early universe further will fall to the James Webb Space Telescope , expected to launch in late 2021. Designed to see even farther back than Hubble because of its powerful infrared vision, Webb promises exciting observations and new discoveries. But our evolving understanding began with Hubble, and a team not afraid to explore what looked like nothing.

  • Jainism and Science | SPACELIA

    How Jainism and Space Science perspectives are matching to each other, The connection between Jainism & Cosmos Jainism and Science In this section we talk about some same points between jainism and science. Similarity You might be wondering what Jainism has to do with science? So now I am going to tell you about such science which was said in Jainism thousands of years ago. You know that science has proved the soul and has told that there is a soul, but this thing is already written in Jainism, let me give you a real life example - "Once a girl was admitted in the hospital. And that girl had come to that hospital for the first time, then that girl woke up in the morning and told what all the things were on the roof of this hospital and how the roof was and explained it completely, the surprising thing is that the roof of that hospital It has been tied for many years and no one needs to know it, then how did that girl know all this? Because the soul of that girl had gone to that rooftop at night. "You might not know that our soul can also travel. This has also been proved by science, and all these things have already been written in Jainism. If you don't believe this then I can show you proof of many other such things. Jain people do not say anything after sunset at night, and you might be finding it unique that why is this so, science also says that one should not eat anything after sunset in the evening, there is a scientific reason for it as well which I will tell you about. Let me explain from the above, you must have seen the sunflower which opens as soon as the sun rises and closes again as soon as the sun sets, our stomach also works in the same way, that is why it is said in Jainism that One should eat after sunrise and not eat after sunset, and this has been proved by science today. And there is one thing which is scientifically proven that we should drink only hot water every day, hot means boiled water, there are many benefits of drinking it and science also accepts this. In our religion it is said to fast after every 15 days and our Lord also used to fast for a long time, a scientist conducted an experiment where some people were made to fast after 15 days and it The result was that the people who fasted were much healthier than the common people and there was a lot of change in their digestive system. Are all these things not enough to say that thousands of years ago, advanced people used to live and those people were none other than our Jains and we should be proud of that. Chat Section......

  • Inflationary Cosmology | SPACELIA

    Inflationary cosmology is a theoretical framework in physical cosmology that proposes a rapid exponential expansion of space in the early universe. It was first proposed by physicist Alan Guth in 1980 to address several puzzles in the standard Big Bang cosmology, such as the horizon problem, the flatness problem, and the origin of structure in the universe. Inflationary Cosmology Theory Concept...... Inflationary cosmology is a theoretical framework in physical cosmology that proposes a rapid exponential expansion of space in the early universe. It was first proposed by physicist Alan Guth in 1980 to address several puzzles in the standard Big Bang cosmology, such as the horizon problem, the flatness problem, and the origin of structure in the universe. The key idea behind inflation is that the universe underwent a brief period of extremely rapid expansion, driven by a hypothetical scalar field called the inflaton. During this inflationary epoch, the universe expanded exponentially, stretching quantum fluctuations to macroscopic scales and smoothing out the curvature and density of space. This expansion also effectively "ironed out" any irregularities in the early universe, explaining the uniformity of the cosmic microwave background radiation observed today. Inflationary cosmology has been supported by a variety of observational data, including measurements of the cosmic microwave background radiation by satellites like the Wilkinson Microwave Anisotropy Probe (WMAP) and the Planck satellite. These measurements have provided strong evidence for the predictions of inflation, such as the nearly scale-invariant spectrum of primordial density fluctuations. Despite its success in addressing many cosmological puzzles, inflationary cosmology is still a subject of active research and debate. There are various models of inflation, each with its own predictions and implications for the universe's early history. Additionally, there are ongoing efforts to test inflationary predictions through observations of the cosmic microwave background, gravitational waves, and large-scale structure in the universe. Some challenges and open questions remain within the framework of inflationary cosmology, including the initial conditions problem (i.e., explaining how inflation started and why the inflaton field had the necessary properties), the reheating mechanism (i.e., how the energy stored in the inflaton field was converted into ordinary matter and radiation), and the so-called "multiverse" implications (i.e., the idea that inflation can lead to the creation of multiple universes with different properties). Overall, inflationary cosmology has had a profound impact on our understanding of the early universe and continues to shape theoretical research in cosmology and particle physics.

  • Black & White Universe | SPACELIA

    How beautiful the space is right?, Yaa it is but not because beautiful colorful looking images, universe has no color in it self, universe is beautiful because we have connection with it with it's mysteries and it's vast expanse. Black & White Universe How beautiful the space is right?, Yaa it is but not because beautiful colorful looking images, universe has no color in it self, universe is beautiful because we have connection with it with it's mysteries and it's vast expanse. All of you must be knowing about the beauty of the universe, how beautiful it looks, have you people gone to space and seen the universe? We only see it in images and this is the truth, right? Not actually, the universe does not look like this from space, it does not look like this, then what is the universe like? And why does it look messy in images? You will get the answers to all these questions today. NASA and other space agencies release many space images and in them space looks like this (Image 1) and it should be exactly like this only then it appears like this in the photo, the universe does not look like this at all, and no objects of the universe (galaxy, star, nebula etc.) have any color of their own, then how do the images look so messed up? Actually telescopes capture infrared rays and they are given color grading through their intensity, high intensity is blue and low is red, and after some such processing those images has become something like this (following picture), so are all these agencies cheating us? No, if the image is black & white then you will not like to see it at all and maybe you are not even that interested in it, and that is why all agencies release color graded images for public release. But space is shown to be very beautiful and peaceful! Movies are for your entertainment and not a science class, so that is why space is shown to be corporeal and beautiful in movies so that your interest remains. So is the view of space shown in Passengers movie not correct? Yes it is an animation, and in fact the view of space shown in all the movies is not correct. How stars are looking bright? There is no color, form or sound of any object in the space because that medium is not available for travelling there, so all the capturing that we do comes in black & white only, you might have this question in your mind that why do stars appear shining?, so the more the intensity of the object will be the more visible to us, like we see the sun which is very close to us and that is why it is visible, similarly the stars have their own light, the brighter the star will be, the brighter its light will be and that is why it appears shining, and this thing is applicable to other objects as well. How Galaxies are looks? Galaxy is so bright because of lots of stars and its glowing center but it doesn’t mean that it looks like this colorful. Same is the principle with galaxy, it doesn’t look so beautiful, even galaxies are not visible, you will not see any shape of galaxy in real life, because we can’t see gases through telescope, we can only see bright things in real form like stars and galaxy center, rest everything is the magic of software, so whenever you see Andromeda in image then remember that it doesn’t look like this as you can see the difference of andromeda galaxy. “The beauty isn’t means the looks everytime, sometimes it means the connection to the UNIVERSE” The universe is expanding, and that expansion stretches light traveling through space in a phenomenon known as cosmological redshift. The greater the redshift, the greater the distance the light has traveled. Within the Hubble Deep Field-North region, astronomers pinpointed a blaze of light from one of the farthest supernovas ever seen. In a close-up view of that region (left) a white arrow points to a faint elliptical, the home of the exploding SN 1997ff. The supernova itself (right) is distinguished by the white dot in the center. This diagram reveals changes in the rate of expansion since the universe's birth 15 billion years ago. The more shallow the curve, the faster the rate of expansion. The curve changes noticeably about 7.5 billion years ago, when objects in the universe began flying apart as a faster rate. Astronomers theorize that the faster expansion rate is due to a mysterious, dark force that is pulling galaxies apart. This image is a portion of the GOODS-North field. The field features approximately 15,000 galaxies, about 12,000 of which are forming stars. Hubble’s ultraviolet vision opened a new window on the evolving universe, tracking the birth of stars over the last 11 billion years back to the cosmos’ busiest star-forming period about 3 billion years after the big bang. Spiral galaxy NGC 3021 (background) was one of several hosts of Type Ia supernovae observed by astronomers to refine the measure of the universe's expansion rate, called the Hubble constant. Hubble made precise measurements of Cepheid variable stars in the galaxy, highlighted by green circles in the inset boxes. Other Articles......

  • Theories | SPACELIA

    Hypothetical Theories of Space Science domain with explanation of those theories. Theories Scientific explanation of any topic Time Is Not Constant only one thing is constant and it is a change. okay for some reason i thought time is constant so when something is come from nothing so nothing is consist nothing not time also. so yes the question is when vacume is consist nothing so time is not constant. but here is a Einstein's Relativity theory is proved wrong as per this perspactive but no everything is right in it's limits. Origin Of Earth Origin of our universe is from big bang effect. and origin of our galaxy is to collab of two galaxies, but origin of our earth is ? , origin of our earth is from sun because age of our galaxy is roughly 13.6 billion years and age of our sun is 4.6 billion years and age of our earth is 4.5 billion years, so the origin of our earth is from sun as per my perspective. exploit on suns surface core is a origin of all planets and asteroids, exploit of sun and other rock is origin of our moon. so this is my basic phenomena. The BIg-Bang Theory The early theory of origin of origin of universe is The Big Bang Theory. which consist a nebular exploidation of two nebulas. this theory is a strongest theory of the origin of universe. when big bang cause dark mater and all galaxies are origin. all things of our universe is cause in this time. scientist strongly work on this theory. Georges Lemaitre || 1894 - 1966 General Relativity Theory The theory of relativity is a scientific theory proposed by Albert Einstein in 1905 and 1915 that fundamentally changed our understanding of space, time, and gravity. It has two main parts: Special relativity: which deals with objects moving at constant speeds, and shows that time is relative to the observer and that objects appear differently depending on the observer's position and motion. General relativity: which deals with the force of gravity and shows that it is not a force at all, but rather the curvature of spacetime caused by the presence of mass and energy. Albert Einstein || 1905 Heat Death Of The Universe The heat death of the universe theory proposes that, over an immense span of time, the universe will gradually reach a state of maximum entropy and energy equilibrium. As the universe expands, the average energy density decreases, leading to a cooling effect. Eventually, all usable energy will be uniformly distributed and no longer available for work or sustaining life. This scenario predicts the loss of structure, complexity, and organization as energy dissipates, resulting in a cold, sparse, and lifeless universe. Lord Kelvin || 1850 Multiness Of Thoughts What we are experiencing right now, whether we have a dream or a thought represents our future, it means that what we think will happen to us, so always keep positive thinking. You may have seen the movie Interstellar where a man controls the fourth diamentio from the future and how our present is connected to our past, this basic concept is what I call the concept of Multiness of Thoughts. this concept is also connected with quantum theories, because this theory also say that all thigs which we see is create with our thoughts and after we see it's die immediately. Quantum Theory Quantum theory, also known as quantum mechanics, is a foundational theory in physics that describes the behavior of particles at the smallest scales. It introduces the concept of quantized energy levels, probabilistic behavior, and the wave-particle duality. Quantum theory revolutionized our understanding of the microscopic world, providing a mathematical framework to calculate probabilities and predict particle interactions. Its applications range from explaining the behavior of atoms and molecules to enabling technologies like quantum computing and quantum cryptography. Quantum theory has fundamentally transformed our understanding of the nature of reality and continues to shape our exploration of the fundamental workings of the universe. Niels Bohr & Max Planck || 1900 Hubble's Law Hubble's Law, named after the astronomer Edwin Hubble, states that galaxies are moving away from us, and the farther they are, the faster they are receding. This law is based on the observation that the light from distant galaxies is shifted towards the red end of the electromagnetic spectrum, known as redshift. Hubble's Law provides evidence for the expansion of the universe and serves as a cornerstone of modern cosmology. By studying the redshift of galaxies, scientists can determine their distance and calculate the rate of cosmic expansion. Hubble's Law has contributed significantly to our understanding of the origin, evolution, and large-scale structure of the universe. Edwin Hubble's || 1929 Cosmic Inflation Cosmic inflation theory proposes that the universe underwent an extremely rapid expansion, known as cosmic inflation, in the earliest moments of its existence. This theory suggests that, shortly after the Big Bang, a tiny patch of space expanded exponentially, causing the universe to rapidly expand and flatten out. Cosmic inflation helps explain several observations, such as the uniformity of the cosmic microwave background radiation and the overall large-scale structure of the universe. It also provides a possible solution to the horizon problem and the flatness problem in cosmology. While cosmic inflation remains a theoretical concept, it has gained widespread acceptance and is considered a crucial component of our current understanding of the early universe. Alan Guth || 1980 String Theory String theory is a theoretical framework in physics that aims to unify all the fundamental forces and particles of nature. It proposes that the fundamental building blocks of the universe are not point-like particles but tiny, vibrating strings of energy. These strings exist in higher-dimensional spacetime and their vibrations give rise to different particles with various properties. String theory offers a promising path towards reconciling general relativity and quantum mechanics, two foundational theories that currently appear incompatible. It also suggests the existence of additional dimensions beyond the familiar three spatial dimensions and one time dimension. String theory is still an area of active research and has sparked numerous developments in theoretical physics, including the concept of holography and new insights into quantum gravity and black hole physics. Gabriele Veneziano || 1969 Dark Matter Theory Dark matter theory proposes the existence of a type of matter that does not interact with light or other forms of electromagnetic radiation but exerts a gravitational influence on visible matter. It is called "dark" because it does not emit, absorb, or reflect light, making it invisible and difficult to detect directly. Dark matter is inferred from its gravitational effects on galaxies and galaxy clusters, explaining the observed rotation curves of galaxies and the dynamics of galactic clusters. The exact nature of dark matter remains unknown, and its composition is a subject of ongoing research. The existence of dark matter is a crucial component in current cosmological models, accounting for a significant portion of the mass in the universe and shaping the large-scale structure we observe. Fritz Zwicky || 1933 Dark Energy Theory Dark energy theory is a concept in physics that attempts to explain the observed accelerated expansion of the universe. It suggests the existence of a mysterious form of energy that permeates all of space and drives this expansion. Dark energy is thought to possess negative pressure, counteracting the gravitational pull of matter and causing the universe to expand at an increasing rate. Its nature and origin remain elusive, with potential explanations ranging from a cosmological constant, as proposed by Einstein, to more exotic possibilities like quintessence or modifications of general relativity. Dark energy constitutes a significant fraction of the total energy density in the universe, but its precise properties and role in cosmic evolution continue to be active areas of scientific investigation. Adam Riess || 1998 Multiverse Theory Multiverse theory is a speculative concept in cosmology and theoretical physics that suggests the existence of multiple universes or parallel realities beyond our own observable universe. According to this theory, each universe within the multiverse could have its own unique physical laws, constants, and properties. The idea of a multiverse arises from attempts to explain various fundamental questions, such as the fine-tuning of physical constants and the origin of our universe. While there are different versions of multiverse theory, they generally propose that the vastness of possibilities extends beyond what we can observe, and that our universe is just one among countless others. The concept of a multiverse is still highly speculative and remains a topic of philosophical and scientific debate, with ongoing research exploring its potential implications and ways to test its validity. William James || 1895 Tagmark's Four Levels of Multiverse The concept of the multiverse is indeed a subject of ongoing scientific exploration and theoretical discussion. Some theories propose different levels or types of multiverse based on various hypotheses, such as: Level I Multiverse: This level of multiverse is based on the idea of an infinite or vastly large universe, where regions far beyond what we can observe contain regions similar to our observable universe. This concept arises from cosmic inflation theory. Level II Multiverse: This level of multiverse is related to the idea of bubble universes within an inflating space. According to eternal inflation theory, our universe could be just one of many "bubbles" embedded in a larger multiverse. Level III Multiverse: This level of multiverse stems from the concept of a "many-worlds interpretation" of quantum mechanics. It suggests that every quantum event spawns multiple parallel universes, resulting in a branching multiverse where every possible outcome of quantum events occurs in a different universe. Level IV Multiverse: This level of multiverse is often associated with the idea of mathematical or logical universes. It suggests that all conceivable mathematical structures or logical systems exist as separate universes. Max Tagmark Apple in a Box Spatial reasoning or problem-solving: In mathematics or logic puzzles, there are scenarios where you might have to imagine an apple placed inside a box and analyze its properties or movements within that confined space. Thought experiment: Philosophers and scientists often use thought experiments to explore concepts and theories. The "apple in a box" could represent a hypothetical situation used to illustrate a particular idea or phenomenon. Teaching tool: Teachers and educators might use the phrase "apple in a box" to simplify complex concepts for students, making it easier for them to understand and visualize abstract ideas. Perception and reality: The phrase might be used metaphorically to explore the difference between what we perceive (the apple in the box) and what objectively exists (the actual state of the apple). Simulation Theory Virtual Reality Hypothesis: Simulation theory proposes that our entire reality, including the universe and all its inhabitants, might be a computer-generated simulation created by an advanced civilization. Technological Mastery: The theory assumes that a highly developed society could create simulations indistinguishable from reality, complete with conscious beings who believe they are living genuine lives. Existential Questions: Simulation theory raises philosophical questions about the nature of consciousness, the meaning of existence, and the potential layers of reality, challenging conventional understandings of the universe. Speculative Nature: While captivating, simulation theory lacks empirical evidence and serves as a thought experiment that encourages us to ponder the nature of reality and our place within an intricate, simulated cosmos. Nick Bostrom | 2003 Special Relativity Theory Special relativity theory, proposed by Albert Einstein in 1905, is a fundamental theory in physics that revolutionized our understanding of space, time, and motion. It introduces two key principles: Constancy of the Speed of Light: The speed of light in a vacuum is the same for all observers, regardless of their relative motion. This means that the speed of light is an absolute constant. Relativity of Space and Time: Space and time are not absolute but depend on the observer's motion. Time can appear to pass differently for moving objects, and lengths can appear shorter when an object moves at high speeds. Special relativity has been extensively tested and confirmed, and it forms the basis for modern physics, helping us understand phenomena at high speeds and near the speed of light. Albert Einstirn || 1905 Twin Paradox The twin paradox is a thought experiment arising from Einstein's theory of special relativity. It involves two identical twins: one stays on Earth, while the other travels into space at a high speed and then returns. Due to time dilation, the traveling twin ages less than the twin who remained on Earth. This seems paradoxical, but it's resolved by considering the effects of acceleration and relative motion on time and space. The twin paradox illustrates the counterintuitive nature of time dilation and the relativistic effects predicted by special relativity. It's been confirmed through experiments and is a fundamental example of how the theory challenges our everyday understanding of time and motion. Quantum Entanglement Quantum entanglement is a bizarre, counterintuitive phenomenon that explains how two subatomic particles can be intimately linked to each other even if separated by billions of light-years of space. Despite their vast separation, a change induced in one will affect the other. In 1964, physicist John Bell posited that such changes can be induced and occur instantaneously, even if the particles are very far apart. Bell's Theorem is regarded as an important idea in modern physics, but it conflicts with other well-established principles of physics. For example, Albert Einstein had shown years before Bell proposed his theorem that information cannot travel faster than the speed of light . Perplexed, Einstein famously described this entanglement phenomenon as "spooky action at a distance." Erwin Schrödinger || 1935 The Infinite Hotel Paradox The Infinite Hotel Paradox is a mind-bending thought experiment in mathematics and philosophy. Imagine a hotel with an infinite number of rooms, and every room is occupied by a guest. When a new guest arrives and wants a room, the manager can still accommodate them by simply asking each current guest to move to the room with a number one higher than their current room. This frees up room 1 for the new guest. What's truly astonishing is that this process can be repeated infinitely, accommodating an infinite number of new guests in a seemingly already full hotel. It challenges our intuitive understanding of finite and infinite quantities, showcasing the paradoxical nature of infinity in a captivating way. David Hilbert's Theory Of Creation The theory of creation, often rooted in religious or mythological beliefs, posits that the universe, Earth, and all living beings were intentionally brought into existence by a divine or supernatural force. Various cultures and religions have their own creation narratives, such as the Judeo-Christian account of God creating the world in seven days, or the Hindu belief in the cosmic dance of Lord Shiva as the source of creation. These theories often serve as explanations for the origins of the cosmos and life itself, offering a framework for understanding our existence and our place in the universe. While the theory of creation is deeply ingrained in cultural and spiritual traditions, it coexists alongside scientific theories of evolution and cosmology, sparking ongoing discussions and debates about the nature of our origins. Charles Darwin || 1859 Grandfather Paradox The grandfather paradox is a thought experiment in the realm of time travel and theoretical physics. It revolves around a hypothetical situation where a person travels back in time and encounters their own grandfather before their grandfather has children. The paradox arises when the time traveler interferes with the past in a way that prevents their own existence. For example, if the time traveler were to prevent their grandparents from meeting or somehow cause their grandfather's death before he could have children, it would create a logical inconsistency. If the time traveler was never born, how could they have traveled back in time in the first place to create the interference? The grandfather paradox raises questions about the nature of time, causality, and the possible consequences of time travel. It's often discussed in discussions about the feasibility and potential paradoxes associated with time travel, but it also highlights some of the challenging problems that arise when contemplating journeys through time. We are nothing.... What is vacuum?, How is vacuum formed?, We believe that there is no air at all in vacuum, meaning vacuum is an empty substance which is completely empty, do you understand this? Wrong, vacuum is not empty matter, vacuum is the space formed by the formation of matter and antimatter. I believe that in this universe of ours, there is an anti-avatar of all the things, like the white hole of the black hole, similarly the anti-matter of the matter. So what are we?, we are also a matter, so can we also have any anti form, absolutely possible, that is why it is called vacuum, and this is how our entire universe is formed, if we say If something came from nothing, then that means we are that nothing. In the end this entire space becomes zero, so can we call ourselves nothing? Chess Square Theory COMING SOON............. Visit Now Parallel World Travel We have heard a lot about time travel, it feels good to hear it but only in imagination and theories, we already know the rest of the reality, but today we have brought another theory in front of you which can happen in the past. There is a thesis based on the above but yes, you will definitely feel happy after reading it. Visit Now We are our GOD This perspective posits that while we are not divine beings, we do possess the capacity to control and manipulate our own destinies, akin to gods in our own right. Drawing parallels with the movie Interstellar, the notion of being the orchestrator of our lives is highlighted. The theory extends to addressing various enigmas such as the Egyptian pyramids and sightings of UFOs, attributing them to our relationship with space. It promises to unravel mysteries and provide answers, though it also emphasizes the importance of mindset in adopting such a worldview. Visit Now The Fermi Paradox The Fermi Paradox is the apparent contradiction between the high probability of extraterrestrial civilizations existing in the vast universe and the lack of any observable evidence or contact with such civilizations. Considering the sheer number of potentially habitable planets, the age of the universe, and the speed at which life emerged on Earth, it seems logical that other advanced civilizations should exist. However, there are various proposed solutions to this paradox, ranging from the possibility that life is rare, to the idea that advanced civilizations self-destruct, or that they communicate in ways we cannot yet detect. Despite extensive efforts, we have not found conclusive evidence of extraterrestrial life, leaving the Fermi Paradox as a major unresolved question in science. Inflationary Cosmology Inflationary cosmology, proposed by Alan Guth in 1980, suggests a rapid expansion of space in the early universe driven by an inflaton field, addressing puzzles in standard Big Bang cosmology. Supported by observations like cosmic microwave background radiation, inflation explains the universe's uniformity and predicts a nearly scale-invariant spectrum of density fluctuations. Challenges include the initial conditions problem and implications for a multiverse, but inflation remains a key area of cosmological research, shaping our understanding of the universe's early history. Visit Now Blackhole Information Paradox The Black Hole Information Paradox presents a fundamental challenge in reconciling quantum mechanics and general relativity within the context of black holes. It arises from the apparent loss of information beyond the event horizon, contradicting the principle of information conservation in quantum mechanics. Proposed solutions include Hawking radiation, the firewall paradox, holographic principles, and theories of quantum gravity such as string theory. Despite ongoing research, a definitive resolution to this paradox remains elusive, representing a crucial frontier in theoretical physics. Visit Now String Theory String theory proposes that fundamental particles aren't point-like but instead tiny, vibrating strings. It attempts to reconcile quantum mechanics and general relativity, aiming for a unified theory of physics. String theory posits extra dimensions beyond the usual three spatial dimensions and one time dimension, offering a framework for understanding the fundamental nature of reality. However, it remains a highly speculative and mathematically complex theory without experimental confirmation. Visit Now

Watching the weather patterns on the giant outer planets (Jupiter, Saturn, Uranus, and Neptune) has been an ongoing activity throughout Hubble’s lifetime. Jupiter's monster storm, the Great Red Spot, was once so large that three Earths would fit inside it. But new measurements by Hubble reveal that the largest storm in our solar system has downsized significantly. The Red Spot, which has been raging for at least a hundred years, is now only the width of one Earth. The storm images were taken in 1995, 2009, and 2014. The images were taken with Wide Field and Planetary Camera 2 (1995) and Wide Field Camera 3. The large Wide Field Camera 2 image of Jupiter was obtained in 2007, with its moon, Ganymede, just emerging from behind the planet. The semi-major axis of Jupiter's orbit about the Sun is 5.2 astronomical units (483 million miles or 778 million km). The planet has a diameter of roughly 88,789 miles (142,984 km) at the equator. This image of Europa is derived from a global surface map generated from combined NASA Voyager and Galileo space probe observations. The graphic shows the location of water vapor detected over Europa's south pole by Hubble in December 2012. The Hubble observations provide the best evidence to date of water plumes erupting off Europa's surface. Hubble didn't photograph plumes, so the plume and the illustration in the center are artist’s conceptions. However, Hubble observers used the Space Telescope Imaging Spectrograph to spectroscopically detect auroral emissions from oxygen and hydrogen. The aurora is powered by Jupiter's magnetic field. This is only the second moon in the solar system found ejecting water vapor from the frigid surface. Another of Jupiter’s moons, Ganymede, is also likely to have a subsurface ocean. Europa is the sixth closest Jovian moon. It is the smallest of the four Jovian satellites discovered by Galileo Galilei, but still the sixth largest moon in the Solar System. Europa was discovered by Galileo in 1610. Images taken in ultraviolet light by Hubble’s Space Telescope Imaging Spectrograph (STIS) show both Jupiter auroras in 1998, the oval-shaped objects in the inset photos. Ground-based telescopes cannot view these phenomena in ultraviolet light, as it is blocked by the Earth’s atmosphere. Auroras are curtains of light resulting from high-energy electrons racing along the planet's magnetic field into the upper atmosphere. The electrons excite atmospheric gases, causing them to glow. The electric-blue image of Jupiter’s northern aurora shows the main oval of the aurora, which is centered on the magnetic north pole, plus more diffuse emissions inside the polar cap. Though the aurora resembles the same phenomenon that crowns Earth's polar regions, the blue Hubble image shows unique emissions from the magnetic "footprints" of three of Jupiter's largest moons. (These points are reached by following Jupiter's magnetic field from each satellite down to the planet). Jupiter has at least 68 moons. Auroral footprints can be seen in this image from Io (along the left-hand limb), Ganymede (near the center), and Europa (just below and to the right of Ganymede's auroral footprint). These emissions, produced by electric currents generated by the satellites, flow along Jupiter's magnetic field, bouncing in and out of the upper atmosphere. They are unlike anything seen on Earth. This ultraviolet image of Jupiter was taken with the Hubble Space Telescope Imaging Spectrograph (STIS) on November 26, 1998. In this ultraviolet view, the aurora stands out clearly, but Jupiter's cloud structure is masked by haze. Saturn’s aurora was observed with Hubble in 2005. Images were obtained with the Advanced Camera for Surveys in the optical and STIS in the ultraviolet. The aurora appeared in Saturn’s southern polar region for several days. Hubble snapped a series of photographs of the aurora dancing in the sky. The snapshots show that Saturn's auroras differ in character from day to day -- as they do on Earth -- moving around on some days and remaining stationary on others. But compared with Earth, where auroral storms develop in about 10 minutes and may last for a few hours, Saturn's auroral displays always appear bright and may last for several days. Recently, NASA’s New Horizons mission imaged Pluto and two of its moons, Nix and Hydra, which were discovered by Hubble in 2005. Peering out to the dim, outer reaches of our solar system beyond Pluto, Hubble uncovered three Kuiper Belt objects (KBOs) that the agency's New Horizons spacecraft could potentially visit after it flies by Pluto in July 2015. The KBOs were detected through a dedicated Hubble observing program by a New Horizons search team that was awarded telescope time for this purpose. The lower set of Pluto images shows Hubble Space Telescope data from the Advanced Camera for Surveys exhibiting an icy, mottled, dark molasses-colored world undergoing seasonal surface color and brightness changes. Pluto has become significantly redder, while its illuminated northern hemisphere is getting brighter. These changes are most likely consequences of surface ice melting on the sunlit pole and then refreezing on the other pole, as the dwarf planet heads into the next phase of its 248-year-long seasonal cycle. Analysis shows the dramatic change in color took place from 2000 to 2002. Note that Hubble found four of Pluto’s five moons – Nix, Hydra, Styx and Kerberos. http://hubblesite.org/newscenter/archive/releases/2014/47/full/ http://hubblesite.org/newscenter/archive/releases/solar-system/pluto/2010/06/ http://hubblesite.org/newscenter/archive/releases/solar-system/pluto/2012/32/ and related links http://www.nasa.gov/nh_new-horizons-spots-small-moons-orbiting-pluto/#.VPnlP2TF_b4 http://pluto.jhuapl.edu/ Other outer solar system objects: Eris is 1.27 times the mass of Pluto, and formerly the largest member of the Kuiper Belt of icy objects beyond Neptune. Hubble observations in 2006 showed that Eris is slightly physically larger than Pluto. But the mass could only be calculated by observing the orbital motion of the moon Dysnomia around Eris. Multiple images of Dysnomia's movement along its orbit were taken by Hubble and Keck. http://hubblesite.org/newscenter/archive/releases/solar%20system/2007/24/image/c/format/web/ Also in 2002, Hubble measured a large object discovered in the outer solar system. It was the largest outer solar system object discovered since Pluto and was superseded by the observation of Eris. Approximately half the size of Pluto, the icy world is called "Quaoar" (pronounced kwa-whar). Quaoar is about 4 billion miles away, more than a billion miles farther than Pluto. Like Pluto, Quaoar dwells in the Kuiper belt, an icy belt of comet-like bodies extending 7 billion miles beyond Neptune's orbit. http://hubblesite.org/newscenter/archive/releases/2002/17/ The upper image, taken by Hubble, reveals the orbital motion of the planet Fomalhaut b. Based on these observations, astronomers calculated that the planet is in a 2,000-year-long, highly elliptical orbit around its parent star, Fomalhaut. The planet will appear to cross a vast belt of debris around the star roughly 20 years from now. If the planet's orbit lies in the same plane with the belt, icy and rocky debris in the belt could crash into the planet's atmosphere. The black circle at the center of the image is caused by a device called a coronograph, which blocks out the otherwise overwhelming light from the bright star and allows reflected light from the belt and planet to be photographed. The Hubble images were taken with the Space Telescope Imaging Spectrograph in 2010 and 2012. Fomalhaut is 25 light years (8 parsecs) away. http://hubblesite.org/newscenter/archive/releases/2013/01/ The lower graphic demonstrates Hubble’s first detection ever of an organic molecule in the atmosphere of a Jupiter-sized planet orbiting another star. This breakthrough is an important step toward eventually identifying signs of life on a planet outside our solar system. The molecule found by Hubble is methane, which under the right circumstances can play a key role in prebiotic chemistry — the chemical reactions considered necessary to form life as we know it. The graphic shows a spectrum of methane with the configuration of the star and the planet (not to scale) in relation to Hubble. The object is 63 light years (19 parsecs) away. http://hubblesite.org/newscenter/archive/releases/2008/11/

  • String Theory | SPACELIA

    String Theory Introduction: String theory represents a revolutionary paradigm shift in our understanding of the universe at its most fundamental level. It endeavors to reconcile the seemingly disparate realms of quantum mechanics and general relativity, offering a unified framework that could elucidate the nature of reality itself. This scientific theory proposes that the basic constituents of the universe are not point-like particles but rather minuscule, vibrating strings. Theory Foundation: At its core, string theory posits that these strings, through their vibrational patterns, give rise to the diverse array of particles and forces observed in the cosmos. By treating particles not as dimensionless points but rather as extended objects with finite size, string theory introduces a novel approach to understanding the fundamental building blocks of matter and energy. Interconnectedness: String theory establishes an intricate web of connections between seemingly disparate phenomena in the universe. The vibrational modes of these strings correspond to different particles and their properties, offering a unified explanation for the diverse spectrum of particles observed in nature. Moreover, string theory suggests the existence of additional spatial dimensions beyond the familiar three, providing a potential framework for understanding elusive phenomena such as dark matter and dark energy. Application at the Atomic Level: At the atomic level, string theory provides insights into the behavior of particles and the underlying forces governing their interactions. By elucidating the vibrational dynamics of strings, physicists aim to unravel the mysteries of particle physics and uncover new phenomena that lie beyond the reach of current experimental techniques. Additionally, string theory offers a fresh perspective on exotic phenomena such as black holes, offering new mathematical tools for understanding these cosmic enigmas. Conclusion: In summary, string theory represents a bold and ambitious attempt to construct a unified theory of physics, capable of describing all fundamental forces and particles within a single, coherent framework. While much work remains to be done to fully develop and validate the theory, its potential implications for our understanding of the universe are profound. String theory continues to inspire scientific inquiry and exploration, offering a tantalizing glimpse into the deepest mysteries of the cosmos. Chat Section If you have any question ask me here....

  • White Hole | SPACELIA

    White holes are theoretical regions of spacetime where matter and energy are thought to emerge outward, representing the hypothetical opposite of black holes. White Hole White holes are theoretical regions of spacetime where matter and energy are thought to emerge outward, representing the hypothetical opposite of black holes. Understanding White Holes: The concept of white holes is a fascinating but theoretical idea within the realm of astrophysics, offering a hypothetical counterpart to black holes in our understanding of the universe. While black holes are regions of spacetime from which nothing can escape, including light, white holes are envisioned as the opposite—a theoretical region where matter and energy can only emerge outward, never to be re-entered. This reversal of the gravitational behavior of black holes forms the basis of the concept of white holes. White holes arise as solutions to the equations of general relativity, which describe the curvature of spacetime in the presence of mass and energy. They represent peculiar regions where spacetime curvature diverges from that of black holes, resulting in the outward flow of matter and energy. However, while the mathematical framework of general relativity supports the existence of white holes, there is currently no observational evidence to confirm their existence. Theoretical models of white holes suggest intriguing properties, including the reversal of time near their central singularities. Whereas black holes represent the ultimate endpoint of gravitational collapse, white holes imply a reversal of this process, with matter and energy emerging outward from a central point. Additionally, some theoretical frameworks propose connections between black holes and white holes through wormholes, hypothetical tunnels in spacetime that could provide passages between different regions of the universe. Despite their theoretical appeal, the existence of white holes remains speculative, and several challenges hinder their direct observation or detection. The extreme conditions required for the formation of white holes, coupled with their theoretical nature, pose significant obstacles to observational studies. Nevertheless, white holes continue to capture the imagination of scientists and cosmologists, serving as intriguing objects that push the boundaries of our understanding of the universe's fundamental laws and the mysteries that lie beyond. How White Hole Forms? The formation of white holes is a speculative concept within theoretical astrophysics, and there are several proposed mechanisms for their origin. One hypothesis suggests that white holes could arise as a result of the reverse process of black hole formation. In this scenario, instead of matter collapsing inward under gravity to form a singularity, external forces or quantum effects prevent further collapse, leading to a rebound or "bounce" that results in the outward expulsion of matter and energy. Another possibility is that white holes could emerge from quantum fluctuations or exotic phenomena in the early universe. During the extreme conditions of the universe's infancy, quantum fluctuations could have given rise to regions of spacetime exhibiting the characteristics of white holes, where matter and energy escape outward rather than collapsing inward. Despite these speculative scenarios, the formation of white holes remains an open question in astrophysics, as their extreme nature and theoretical properties pose significant challenges to observational confirmation. Further research and theoretical investigations are needed to elucidate the mechanisms behind white hole formation and their potential role in the cosmos. Is a White Hole connected to a Black Hole? The concept of a black hole being connected to a white hole on the other side is often discussed in theoretical physics and science fiction, but it remains speculative and has not been supported by observational evidence. This idea is based on the theoretical possibility of a wormhole—a hypothetical tunnel-like structure in spacetime that could connect two distant points or even different universes. Here's how the concept of a black hole connected to a white hole through a wormhole is typically envisioned: Wormholes: Wormholes are theoretical solutions to the equations of general relativity that suggest the existence of shortcuts or tunnels through spacetime. These structures would allow matter, energy, or information to travel between distant regions of the universe more quickly than would be possible through normal space. Black Hole Throat and White Hole Throat: In the context of a black hole connected to a white hole, the black hole's event horizon is considered the entrance or "throat" of the wormhole, while the white hole's event horizon is considered the exit or "throat" of the wormhole. One-Way Passage: Theoretical models of this scenario typically involve a one-way passage of matter and energy through the wormhole, with objects falling into the black hole's event horizon emerging from the white hole's event horizon. This setup resembles the behavior of a black hole and a white hole in isolation, where matter falls into the former and escapes from the latter. Cosmological Implications: If black holes and white holes are indeed connected through wormholes, it would have profound implications for our understanding of the universe's structure and dynamics. It could provide a mechanism for the transfer of matter, energy, or even information between different regions of spacetime or even different universes. Speculative Nature: While the concept of black holes connected to white holes through wormholes is mathematically consistent with the laws of general relativity, there is currently no observational evidence to support its existence. Wormholes are highly speculative and remain purely theoretical constructs at this point. Overall, while the idea of a black hole being connected to a white hole through a wormhole is fascinating and has captured the imagination of scientists and science fiction writers alike, it remains speculative and requires further theoretical and observational investigation to determine its validity. Theoretical researches on White Hole : Research on white holes primarily falls within the realms of theoretical physics and cosmology, as there is currently no observational evidence for the existence of white holes. However, scientists have proposed various theories and explored different aspects of white holes within the framework of general relativity and quantum mechanics. Here are some key areas of research and theories related to white holes: Mathematical Analysis: Much of the research on white holes involves mathematical analysis within the framework of general relativity. Scientists have derived theoretical solutions to the Einstein field equations that describe the geometry of spacetime in the presence of a white hole. Relationship to Black Holes: One prominent area of research involves exploring the relationship between black holes and white holes. Some theoretical models suggest that black holes and white holes may be connected through wormholes, hypothetical tunnels in spacetime that could allow matter and energy to travel between them. Hawking Radiation Reversal: Analogous to black holes emitting Hawking radiation, some theories propose that white holes could absorb radiation and matter from their surroundings, leading to a reversal of the Hawking radiation process. This idea is speculative and remains an area of active research. Formation Mechanisms: Scientists have proposed various mechanisms for the formation of white holes. Some theories suggest that white holes could arise as the reverse process of black hole formation, while others speculate that they may emerge from quantum fluctuations or other exotic processes in the early universe. Cosmological Significance: White holes have been proposed as potential explanations for phenomena such as gamma-ray bursts, extremely energetic events observed in distant galaxies. Researchers continue to explore the cosmological implications of white holes and their potential role in the evolution of the universe. Quantum Gravity: Understanding the behavior of white holes may provide insights into the quantum nature of gravity and the unification of quantum mechanics and general relativity. Investigating white holes within the framework of quantum gravity theories, such as loop quantum gravity or string theory, remains an area of active theoretical research. Multiverse Hypothesis: Some speculative cosmological models, such as the multiverse hypothesis, suggest that white holes could be connected to other universes within a larger cosmic ensemble. Research on white holes intersects with broader discussions about the nature of the multiverse and the possibility of other universes beyond our own. Overall, research on white holes spans a wide range of theoretical and conceptual domains within physics and cosmology. While white holes remain hypothetical constructs, exploring their properties and implications contributes to our understanding of the fundamental nature of the universe. Is the White holes are the creator of our universe? The concept of white holes serving as creators of the universe is a speculative idea that lacks empirical evidence and remains largely confined to theoretical discussions. While white holes are theoretical constructs derived from general relativity, positing them as sources from which matter and energy emanate outward, there is no scientific substantiation for their role as the creators of the universe. The prevailing cosmological understanding, rooted in the Big Bang theory, describes the universe's origin as an immensely dense and hot state expanding from a singularity around 13.8 billion years ago. This model does not incorporate white holes as fundamental to universal creation. White holes, if they exist, are envisioned as regions of spacetime where matter and energy escape rather than enter. While the idea of white holes as creators may be intriguing, it remains speculative and lacks empirical support. Other cosmological hypotheses, such as inflationary cosmology or multiverse theories, provide alternative explanations for the universe's origins without invoking white holes. Therefore, while the concept stimulates theoretical discourse, it currently lacks empirical validation and is not widely accepted within the scientific community. White Holes are not possible in Quantum Physics: In the realm of quantum physics, the concept of white holes faces significant challenges due to the fundamental principles governing quantum mechanics. Quantum physics describes the behavior of matter and energy at the smallest scales, where traditional notions of spacetime curvature may break down. One key challenge is reconciling the deterministic nature of general relativity, which underpins the concept of white holes, with the inherent uncertainty and probabilistic behavior inherent in quantum mechanics. Additionally, white holes are associated with extreme gravitational conditions and singularities, where quantum effects are expected to become significant. However, current quantum gravity theories, such as loop quantum gravity or string theory, have not yet provided a complete framework for describing the behavior of spacetime near singularities or within the context of white holes. Therefore, while quantum physics offers valuable insights into the nature of the universe, the theoretical challenges inherent in combining quantum mechanics with general relativity present obstacles to the existence of white holes within a purely quantum framework.

  • Jain geography | SPACELIA

    The universe for Jains is an elaborate system. Jain cosmology is very distinctive, although it shares some features with other Indian religious traditions. It is centred on the everlasting and non-originating nature of the universe, and thus excludes the notion of a creator-god. Jain geography All about Jain's geography and space science Introduction The universe for Jains is an elaborate system. Jain cosmology is very distinctive, although it shares some features with other Indian religious traditions. It is centred on the everlasting and non-originating nature of the universe, and thus excludes the notion of a creator-god. As written by a leading monastic figure from the 12th century, ‘the universe having the shape of a man standing with arms akimbo, with feet apart, filled with substances continuously being created, preserved and destroyed, has never been produced by anyone and is not sustained by anyone either. It exists by itself, without any support’.[1] Although Jains do not worship a creator-god, deities do exist, as mediators between the perfected souls of the Jinas and the imperfect world of human experience, and are a part of the Jain cosmology. Structure of the Jain Universe The Jains distinguish two types of space. The first is the world space (loka-ākāśa), which is a vast but limited area where all souls live in the different body-forms they take according to their rebirths in the various worlds. The second is the non-world space (aloka-ākāśa), which is endless. The Jain universe is perfectly structured and ordered. One of its governing principles is symmetry and repetition, so that ‘to know one part is to know the whole’. It can be viewed as ‘a self-replicating composite’ with, for example, a northern region the exact replica of its southern counterpart, halves being identical, etc. The Jain universe is thought of in terms of dimensions and quantities of units. Jain thinkers have produced a vast vocabulary to describe and understand units of time and space, going from the smallest to the largest, beyond what can be imagined. The smallest unit is the atom. Infinite combinations of atoms make up the smallest unit of measurement. At the other extreme, Jains have devised a refined analysis of extremely large numbers, considering the numerable, the innumerable and the infinite. Jain cosmology gives an important place to mathematical concepts and calculations, so that mathematical treatises written by the Jains may take their illustrative examples from cosmological contexts. Śvetāmbaras and Digambaras agree on the structure of the universe and its elements but differ on many names and numbers. Grasping Jain cosmology is vital to understanding the Jain religion. The soul is an innately pure substance. But, due to embodiment and activity, good or bad, it accumulates karma, which in the Jain understanding means physical matter. This alters the purity of the soul and generates cycles of rebirths within the universe until this finally ends. Rebirth can take one of the following four forms of destiny (gati): 1. as a human (manuṣya); 2. as an inhabitant of the hells (naraka); 3. as a deity (deva); or 4. as an animal or plant (tiryag). Spiritual progression requires an understanding of these cosmological theories. Contemplating the universe is also included within the system of reflection-topics (anuprekṣā). Jambudweep This topic can not be logically or physically proven. It can only be understood on the base of Aagam Vani. You may not be able to beleive it if you think it from modern view as it exists right now. This has to be taken on faith to understand and the main foundation of its understanding is Kevalgyan. Two vertical lines are Tras Nadi where Tras Jeev live. This is in the middle with 13 Raju height. Not covering 1 Raju at the top. Every structure we understand or is described is contained within Tras Nadi. Everything outside is only 1 sensory Jeev called Sthavar Jeev. Middle part is Madhya Lok. Middle Earth. 5 Meru parvat in the middle. Sudarshan Meru/Sumeru is the basis of differentiation of 3 Lok. Madhyalok height is defined by Sumeru Parvat. Below it is Adholok. Above it is Urdhvalok. Physical Dimensions: Bottom – 7 Raju Middle – 1 Raju Up Middle – 5 Raju Top – 1 Raju Depth – 7 Raju Height – 14 Raju Volume 343 Raju^3 Scale: Raju/Rajju is a measurement unit. 1 Raju = Infinite Yojan 1 Yojan = 2000 Kos 1 Kos = 2 Miles 1 Mile = 1.64 Km Strange Facts In front of Jain Geography, the principles and discoveries of our science and space become false, because in Jain Geography, the house is considered as a divine plane, whatever nature the house has, that plane will also be of that type, and in the same way in Jain Geography The sun is considered as the plane of heat and the moon as the plane of coolness and an interesting fact about it is that in Jain geography there are two suns and two moons. According to Jainism, man can never go to the Moon or any other planet! Yes, you are listening right, I know that it sounds very different, but it is not a matter that these things are only heard somewhere, this principle is also a reality in Puranas and the map you are seeing above is also Jambudweep. It is from Another special thing in this is that in the middle of Jambudweep, there is Mount Meru, at some distance of which all the things of this universe are present, and according to this, we humans can never reach this sacred plane and all the other things, there is also a solid proof of this. There is a reason which I will tell you later. Yes, I know you will definitely be shocked to hear all this, but it is true and there is also one thing that Jain geography is very different and unique from our modern space science, but I will tell you further in the rest of the information. Who created our Universe according to Jainism No, as per Jainism Universe is eternal. It's neither created nor shall it ever collapse. Now to the question, i.e. what led to the creation (read structure) of the universe ? To keep things simple, we will just concentrate on the middle world where we humans live as it will help us better understand the structure and operations of the universe on the foundations of our current knowledge on the subject. What is outside of the Universe Well, that would define how you describe the universe as. As per Jainism, the universe consists of broadly two regions viz Lokakash and Alokakash 1st region Lokakash is the region that consists of all things made of a material that exhibits the property of Fusion (Pud) and Fission (Gal) which we call matter today. Its this region of the universe that hosts our planet and all other alien habitable planets that support intelligent lifeforms, along with higher and lower planes where demigods and hellish beings reside.

  • Hubble's Nebulae | SPACELIA

    Hubble's Nebulae Hubble telescope discovered some nebulae here is an image and detail of the nebulae and other information about it. Emission Nebulae Emission nebulae are so named because they emit their own light. This type of nebula forms when the intense radiation of stars within or near the nebula energizes the gas. A star’s ultraviolet radiation floods the gas with so much energy that it strips electrons from the nebula’s hydrogen atoms, a process called ionization. As the energized electrons revert from their higher-energy state to a lower-energy state by recombining with atoms, they emit energy in the form of light, causing the nebula’s gas to glow. A famous example of an emission nebula is the Orion Nebula, a huge, star-forming nebula in the constellation Orion. The Orion Nebula is home to a star cluster defined by four massive stars known as the Trapezium. These stars are only a few hundred thousand years old, about 15-30 times the mass of the Sun, and so hot and bright that they’re responsible for illuminating the entire Orion nebula. But thousands of additional, mostly young stars are embedded in the nebula. The most massive are 50 to 100 times the mass of our Sun. The radiation and solar winds of stars within emission nebulae carve and sculpt the nebula’s gas, creating caverns and pillars but also creating pressures on the gas clouds that can give rise to more starbirth. Reflection Nebulae Reflection nebulae reflect the light from nearby stars. The stars that illuminate them aren’t powerful enough to ionize the nebula’s gas, as with emission nebulae, but their light scatters through the gas and dust causing it to glow ― like a flashlight beam shining on mist in the dark. Because of the way light scatters when it hits the fine dust of the interstellar medium, these reflection nebulae are often bluish in color. A reflection nebula called NGC 1999 lies close to the famous Orion Nebula, about 1,500 light-years from Earth. The nebula is illuminated by a bright, recently formed star called V380 Orionis, and the gas and dust of the nebula is material left over from that star’s formation. A second well-known reflection nebula is illuminated by the Pleiades star cluster. Most nebulae around star clusters consist of material that the stars formed from. But the Pleiades shines on an independent cloud of gas and dust, drifting through the cluster at about 6.8 miles/second (11 km/s). Planetary Nebulae When astronomers looked at the sky through early telescopes, they found many indistinct, cloudy forms. They called such objects “nebulae,” Latin for clouds. Some of the fuzzy objects resembled planets, and these earned the name “planetary nebulae.” Today these nebulae keep the name, but we know they have nothing to do with planets. Planetary nebulae form during the death of low-mass to medium-mass stars. When such stars die, they expel their outer layers into space. These expanding shells of gas form a huge variety of unique shapes ― rings, hourglasses, rectangles, and more ― that show the complexity of stellar death. Astronomers are still studying how these intricate shapes form at the end of a star’s life. As the star casts off its outer layers, it leaves behind its core, which becomes a white dwarf star. White dwarf stars are objects with the approximate mass of the Sun but the size of Earth, making them one of the densest forms of matter in the universe after black holes and neutron stars. The white dwarf star’s ultraviolet radiation ionizes the gas of the planetary nebula and causes it to glow, just as stars do in emission nebulae. Our Sun is expected to form a planetary nebula at the end of its life. Supernova Remnants Not all stars die gently, exhaling their outer layers into space. Some explode in a supernova, flinging their contents into space at anywhere from 9,000 to 25,000 miles (15,000 to 40,000 kilometers) per second. When a star has a lot of mass ― at least five times that of our Sun ― or is part of a binary system in which a white dwarf star can gravitationally pull mass from a companion star, it can explode with the brightness of 10 billion Suns. Supernova remnants consist of material from the exploded star and any interstellar material it sweeps up in its path. The new debris from the explosion and material ejected by the star earlier in its life collide, heating up in the shock until it glows with x-rays. Supernova remnants’ glow can also be powered by the stellar wind of a pulsar ― a rapidly spinning neutron star created from the core of the exploded star. The pulsar emits electrons that interact with the magnetic field it produces, a process called synchrotron radiation, and emits X-rays, visible light and radio waves. Absorption Nebulae Absorption nebulae or dark nebulae are clouds of gas and dust that don’t emit or reflect light, but block light coming from behind them. These nebulae tend to contain large amounts of dust, which allows them to absorb visible light from stars or nebulae beyond them. Astronomer William Herschel, discussing these seemingly empty spots in the late 1700s, called them “a hole in the sky.” Included among absorption nebulae are objects like Bok globules, small, cold clouds of gas and dense cosmic dust. Some Bok globules have been found to have warm cores, which would be caused by star formation inside, and further observation has indicated the presence of multiple stars of varying ages, suggesting a slow, ongoing star formation process. The Crab Nebula is an example of a supernova remnant. The explosion that created it in the year 1054 was so bright that for weeks it could be seen even in the daytime sky, and it was recorded by astronomers across the world. The material from the star is still rushing outward at around 3 million mph (4.8 million kph). Hubble's Nebulae Gallery

  • Blackhole Information Paradox | SPACELIA

    The Black Hole Information Paradox is a long-standing problem in theoretical physics and astrophysics, concerning the conservation of information in the presence of black holes, which are regions of spacetime where gravity is so strong that not even light can escape from them. The paradox arises from the clash between the principles of quantum mechanics and general relativity.

The paradox arises from the clash between the principles of quantum mechanics and general relativity. In classical physics, black holes are described by solutions to Einstein's field equations of general relativity, which predict that anything that falls into a black hole will be irretrievably lost behind its event horizon, a boundary beyond which nothing can escape. This implies that any information about the matter that formed the black hole, such as its mass, charge, and angular momentum, is lost to the outside universe. However, according to the principles of quantum mechanics, information cannot be destroyed. Instead, it should always be possible, in principle, to trace the evolution of a quantum system backwards in time and reconstruct the initial state from the final state. This principle is known as unitarity. The paradox arises because the classical description of black holes seems to violate the principles of quantum mechanics. If information is lost behind the event horizon, then the evolution of a black hole's state seems to violate unitarity, leading to a breakdown of quantum mechanics. Various proposed solutions to the Black Hole Information Paradox have been put forward over the years, but none have been universally accepted. Some of these proposals include: Hawking Radiation and Information Loss: Stephen Hawking proposed that black holes emit radiation (now known as Hawking radiation) due to quantum effects near the event horizon. This radiation carries away energy from the black hole, eventually causing it to evaporate completely. Initially, it was believed that this process led to the loss of information, but later work suggested that information might be encoded in the radiation, leading to the idea of "black hole complementarity" or the "firewall paradox." Firewall Paradox: Proposed as a resolution to the information paradox, the firewall paradox suggests that an observer falling into a black hole would encounter a firewall of high-energy particles at the event horizon, contradicting the smooth spacetime predicted by general relativity. This proposal has sparked significant debate within the physics community. Holographic Principle and AdS/CFT Correspondence: The holographic principle suggests that all the information contained within a region of space can be encoded on its boundary. The AdS/CFT correspondence, a conjectured equivalence between certain gravitational theories and quantum field theories, has been used to study black hole physics in this context, offering potential insights into the resolution of the information paradox. Quantum Gravity and String Theory: Some researchers believe that a theory of quantum gravity, which successfully unifies quantum mechanics and general relativity, could resolve the information paradox. String theory is one candidate for such a theory, but it remains highly speculative and has not yet been definitively confirmed. Information Preservation: Other proposals suggest that information may somehow be preserved in a subtle way within the black hole or its radiation, allowing for the eventual recovery of the initial state.Despite decades of research, the Black Hole Information Paradox remains unsolved, and it continues to be a topic of active investigation and debate within the physics community. Resolving this paradox is crucial for developing a complete understanding of the fundamental laws governing the universe. Chat Section If you have any question ask me here.... Other Articles......

  • Answer of the Arecibo Message | SPACELIA

    In 1974, humanity took a bold step into the unknown. From the Arecibo Observatory in Puerto Rico, a powerful radio signal pierced the night sky. This wasn’t your typical astronomical observation; it was a deliberate message aimed at the vast emptiness of space, carrying a beacon of our existence. This message, known as the Arecibo message, became a landmark event in our search for extraterrestrial intelligence (SETI). Answer of the Arecibo Message Messages to the Stars: Humanity’s Search for Cosmic Connection For as long as humans have gazed at the stars, we’ve wondered if someone—or something—is looking back. This timeless question has fueled art, science, and philosophy for centuries, driving efforts to make contact with whatever might be out there. From real scientific milestones to intriguing mysteries and fictional narratives, humanity’s quest to communicate with the cosmos continues to inspire and captivate. Let’s explore three iconic examples of this endeavor: the Arecibo Message, the mysterious Chilbolton Message, and the imaginative response portrayed in the movie Contact. 1. The Arecibo Message: Humanity’s First Call to the Stars In 1974, scientists sent a groundbreaking message from the Arecibo Observatory in Puerto Rico—a binary-coded signal designed to introduce humanity to any extraterrestrial civilization capable of decoding it. Directed at the M13 star cluster, located 25,000 light-years away, this broadcast was humanity’s first deliberate attempt to communicate across interstellar space. The message contained: Our numeric system (1 to 10) Key elements of life like hydrogen, carbon, nitrogen, oxygen, and phosphorus The structure of DNA, showcasing its double-helix configuration A depiction of a human figure alongside Earth’s population Earth’s position in the solar system A representation of the Arecibo telescope as the source of the message Though it was largely symbolic, the Arecibo Message was a bold statement of our curiosity and technological progress, underscoring humanity's hope that we are not alone. 2. The Chilbolton Message: A Mystery in the Fields Fast-forward to August 2001, when something remarkable appeared near the Chilbolton radio telescope in Hampshire, England—a mysterious crop formation. Unlike typical crop circles, this one seemed to be a direct response to the Arecibo Message. The formation mirrored the structure of the original message but contained key differences: A modified DNA sequence, suggesting a different biological makeup. A planetary system with additional planets, hinting at an alternate origin. An image of a humanoid figure, distinct from the human depiction in the original message. Despite widespread skepticism and claims of a hoax, the Chilbolton Message intrigued scientists and the public alike. It reignited the imagination, sparking debates about extraterrestrial communication and the lengths humanity might go to uncover cosmic truths. 3. The Answer in Contact: A Visionary Narrative In the realm of fiction, the movie Contact (1997) offered a profound exploration of what an actual reply to the Arecibo Message might look like. Based on Carl Sagan's novel, the story follows Dr. Ellie Arroway as she receives a signal from an intelligent extraterrestrial source. The message in Contact contains: Prime numbers, confirming an intelligent origin. Human DNA sequences, a reflection of shared understanding. Instructions to build a machine, capable of enabling interstellar travel. The narrative transcends science, delving into emotional and philosophical themes. It challenges viewers to consider not only the implications of discovering intelligent life but also how it might transform humanity’s understanding of itself. What These Messages Mean for Humanity Whether real, mysterious, or fictional, these messages symbolize humanity’s deep yearning to connect with the unknown. The Arecibo Message demonstrates our technological advancements and hope for contact. The Chilbolton Message, regardless of its authenticity, underscores our fascination with the possibility of extraterrestrial communication. Meanwhile, Contact invites us to imagine the emotional and philosophical weight of finding we are not alone. As we continue to explore the cosmos, these stories remind us that the quest for connection defines who we are. Every signal sent, every mystery pondered, and every story told brings us closer to understanding our place in the universe. Other Articles......

  • Black Hole | SPACELIA

    Explore Black Hole BLACK HOLE A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it. They are formed when massive stars collapse under their own gravity at the end of their life cycle. Black holes can vary in size, from small ones, called stellar black holes, to supermassive black holes that reside at the centers of galaxies. Despite their mysterious nature, scientists study black holes to understand the laws of physics and the universe's evolution. intriguing properties continue to captivate researchers and space enthusiasts alike. Sagittarius A Sagittarius A* (Sgr A*) is a supermassive black hole at the center of the Milky Way galaxy. It's located in the constellation Sagittarius, more than 25,000 light years from Earth. Messier 87 The Messier 87 (M87) galaxy, located 55 million light-years away, contains a supermassive black hole, M87*, which was the first ever imaged, showing a bright ring surrounding a dark central region, and is also known for its powerful jet of plasma. Cygnus X-1 Cygnus X-1 is a well-known black hole X-ray binary system, discovered in 1964, and is considered the first object identified as containing a black hole. It's located in the constellation Cygnus, about 7,000 light-years from Earth. V404 Cygni V404 Cygni is a black hole system located about 8,000 light-years away in the constellation Cygnus, recently discovered to be part of a rare triple star system, containing a black hole, a companion star, and a distant tertiary star. TON 618 TON 618 is a hyperluminous, broad-absorption-line, radio-loud quasar powered by a supermassive black hole, estimated to be 66 billion times the mass of our Sun, located about 18.2 billion light-years away. Abell 1201 Astronomers discovered an ultramassive black hole, roughly 32.7 billion times the mass of our Sun, in the center of Abell 1201 BCG, a massive elliptical galaxy within the galaxy cluster Abell 1201, using gravitational lensing.

  • Space Facts | SPACELIA

    Facts about Space Facts about space, new planets, antique thing in space, new updates The great attractor Location: The Great Attractor is located in the direction of the Centaurus and Hydra constellations, roughly 150 million light-years away from Earth. Its position behind the dust clouds of our Milky Way galaxy makes it challenging to observe directly. Gravitational Pull: The Great Attractor possesses an immense gravitational force that influences the motion of nearby galaxies. It acts as a massive attractor, causing galaxies to move towards it at high speeds. This gravitational pull shapes the large-scale structure of the universe. Uncertain Nature: The exact nature and composition of the Great Attractor remain a mystery. Scientists propose various theories, including the possibility of it being a concentration of dark matter or a supercluster of galaxies. Further research and observations are necessary to unravel the true nature of this cosmic phenomenon. Age of water A fascinating fact about the age of water on Earth is that some of the water molecules we have today are estimated to be as old as the solar system itself. This conclusion is based on the analysis of isotopes, specifically the ratios of deuterium (a heavy isotope of hydrogen) to regular hydrogen in water samples. By studying these isotopic ratios, scientists have determined that a portion of Earth's water has likely been part of the planet's hydrological cycle since its formation approximately 4.5 billion years ago. This means that the water we use and encounter every day has been cycling through the Earth's oceans, atmosphere, and land for billions of years, making it a remarkable and ancient resource. Gliese 436 B Classification: Gliese 436 b is classified as a "hot Neptune" due to its size resembling Neptune, but with extreme temperatures. Orbit and Distance: It orbits very close to its parent star, completing a revolution in just 2.64 Earth days. Gliese 436 b is located approximately 33 light-years away from Earth. Atmosphere and Composition: The planet has a scorching atmosphere due to its close proximity to the star. It is primarily composed of hydrogen and helium, but also contains exotic materials such as "hot ice" or superheated steam. Density and Structure: Gliese 436 b has a relatively low density compared to other exoplanets of similar mass and size. The planet may have a dense core surrounded by a massive envelope of hydrogen and helium. Tidal Forces: Strong tidal forces act on the planet due to its proximity to the star. These tidal forces elongate the planet, leading to additional heating of its atmosphere. The oldest planet Age: PSR B1620-26 system is estimated to be around 12.7 billion years old. Star: The system's central star is a binary system consisting of a pulsar (PSR B1620-26) and a white dwarf. Planets: PSR B1620-26 b (Methuselah): Discovered in 2003. Gas giant planet. Similar in size to Jupiter. Mass is approximately 2.5 times that of Jupiter. Orbits both the pulsar and the white dwarf. Average distance from the star: about 23 astronomical units (AU). Highly eccentric orbit. Orbital period: roughly 100 Earth years. PSR B1620-26 c (Genesis): Discovered in 2006. Gas giant planet. Orbits at a distance of approximately 83 AU from the central stars. GJ 1214B Discovery: GJ 1214b was discovered in 2009 by the MEarth Project, which aims to detect Earth-sized exoplanets orbiting nearby M-dwarf stars. Classification: GJ 1214b is classified as a super-Earth exoplanet. Size and Mass: GJ 1214b is larger than Earth but smaller than gas giants like Jupiter. Its size is approximately 2.7 times the Earth's radius. The mass of GJ 1214b is estimated to be around 6.5 times the mass of Earth. Composition: GJ 1214b is believed to have a substantial atmosphere. The planet's composition consists of a combination of rock and water. HD 140283 Age: HD 140283 is one of the oldest known stars in the universe. Its estimated age is about 14.46 billion years, making it older than the estimated age of the universe itself. Distance: HD 140283 is located approximately 190 light-years away from Earth. It is situated in the constellation Libra. Spectral Class and Subgiant Status: HD 140283 is classified as a subgiant star. It belongs to the spectral class F9, indicating its temperature and other Speciality: This planet is the oldest planet of our universe, in fact this planet is older than universe Deja Vu effect Deja vu is a psychological phenomenon characterized by a strong sense of familiarity or the feeling that one has experienced a current situation or event before, despite knowing that it is impossible. While the exact cause of deja vu is not fully understood, several theories have been proposed to explain its occurrence. Here are some of the leading theories: Prevalence: Deja vu is a common phenomenon experienced by a significant portion of the population. Studies suggest that approximately 60-80% of people report having had at least one deja vu experience in their lifetime. Milkey way galaxy The Milky Way Galaxy was born about 12.7 years ago, and is still expanding rapidly today. According to scientists, 6 to 7 new stars are born every year in our milky way galaxy and every year a light star dies and turns into a planetary nebula. Our solar system is 27,000 light years away from the center of the Milky Way galaxy. Our milky way galaxy travels through space at a speed of about 583 KM/S, and it is expanding at a speed of 1770 KM/H. At the center of our Milky Way galaxy is the SAGITTARIUS A* black hole with a mass 4.3 million times that of our Sun. Speed of Light The speed of light in a vacuum is approximately 299,792,458 meters per second (or about 186,282 miles per second). This speed is denoted by the symbol "c" in physics equations. Light travels at a constant speed in a vacuum, regardless of the source or the observer's motion. This is one of the fundamental principles of physics. The speed of light is incredibly fast. For example, light from the Sun takes about 8 minutes and 20 seconds to reach Earth, even though the distance is about 93 million miles (150 million kilometers). The speed of light is the fastest known speed in the universe. According to our current understanding of physics, no object with mass can reach or exceed the speed of light. Travel at speed of light If we travel at the speed of light, what will the universe look like, then understand that when we drive in the rain, the rain water hits the windshield of the car, as the speed of the car increases, the water hits more diagonally and today The concept applies to spaceships and interstellar space in the universe, where the spaceship traveling at the speed of the universe appears in 2D form in a frame against the light of the surrounding stars. MIT University has done one such fun experiment in which it has shown what it feels like to go back and forth at the speed of light. (Download link is below) Download A Slower Speed of Light game: https://gamelab.mit.edu/games/a-slower-speed-of-light/ Speed of Light 2 The fastest moving thing in our universe is light, which moves at a speed of 300,000 kilometers per second. You will be surprised to know that light takes 1.3 seconds to reach the moon from earth and it takes 182 seconds to reach Mars and it takes 32 minutes to reach Jupiter and it takes 500 years to reach our Milky Way Galaxy. Light takes 2500000 years to go and reach the nearest Galaxy Andromeda and you will be surprised to hear that despite the speed of light, it can never cross the universe because our universe is spreading faster than light. Time Dilation What is time dilation? Let us understand in a very simplified way, you must have seen the Interstellar movie, in which time is extremely slow on the planet named Millers, where 1 hour spent is equal to 7 years spent on Earth. This is because the planet was very close to the black hole, according to Einstein's theory of relativity, black holes have more time warp, so that time slows down. So understand it in this way that it normally takes us time to go from point A to B, but if we pass near a black hole, then the curvature increases, so it takes more time for us to go from A to B. Epsilon Eridani Star System 7th Aug 2000 Scientists have discovered a new star system named Epsilon Eridani in the Eridanus constellation about 10.5 light years away from Earth. This star system is exactly like our solar system. In this star system we have discovered Epsilon Eridani-b and a low mass planet Epsilon Eridani-c like Jupiter. Apart from this, the asteroid belt is also present in this star system just like our solar system. About 800 million years old, this star system is similar to the time when life began on our Earth. Scientists also consider this star system as the home of aliens. Strange Planets The Pink Planet : GJ504B is a planet that looks completely pink in color and the reason for the pink appearance of this house is its intense heat which makes it look pink, and this planet is 4 times bigger than Jupiter. Super Saturn : J1407B is also called Super Saturn because this planet has the largest planetary ring system ever found and this ring system is 640 times bigger than Saturn. The golden planet : 16 psyche is an asteroid, but it is also called a minor planet. There is a lot of gold in this asteroid. Let us tell you that the price of this minor planet is about 700 quintillion dollars. Space Facts-1 Right now we know only 5% of the universe out of 100 hubs and this is what we call the observable universe and according to scientists there are about 2 trillion galaxies in our observable universe. 1 billion 400 million years ago, a day on our earth used to be 18 hours 41 minutes. There are thousands of millions of black holes present in our Milky Way Galaxy, which keep wandering in space like this. HD140283 is considered to be the first star of this universe and the age of this star is 14.3 billion years which is more than the age of our universe. The black hole that is closest to our earth is named HR6819 and this black hole is 1000 light years away from us. PSR J1719 1438B In the year 2009, MATHEW BAILES, who is an astrophysicist, saw a house from his telescope which was 3000 times bigger than the sun, yet it was revolving around its sun, then after research, it was found that in a supernova explosion, that star was transformed into a nevtron star, whose mass is much more than its house, so it is holding its star despite being small, and that planet has also become a super giant, but due to the heat of its star. Since then the carbon inside it has now become diamond and that planet is a complete diamond planet. Center of Mass in Solar System We all have been reading since childhood that all the planets in our solar system revolve around the Sun, so according to that, the middle point for all the planets should be the middle point of the Sun, but it is not so in reality. Gravitational force pulls the planet towards itself, similarly the planets also pull the Sun, but here the Sun is an ancient and very big star, so its force is more than all the other planets, hence all the planets are seen revolving around it, but all the planets And the center of mass between the Sun is different, like Jupiter is the largest planet in our solar system, so as soon as its gravitational force and the force of the Sun meet, both of them revolve around their center of mass which is away from the center of the Sun. Comes a little further. Time Traveler Party The great scientist Stephen Hawking was already experimenting on time travel. In 2009, Stephen Hawking hosted a reception for time travelers at the University of Cambridge. He sent out invitations but did not publicize the event until afterward. The idea was to see if any time travelers would attend, as they would be aware of the event's details through time-traveling knowledge. But no one attended that party which proved that humans cannot time travel. And we also know that if we have to go back in time then it is never possible in the universe. What is Time? Time!, what is time? You will say that a clock or a calendar will be something like this, no, time is not a thing, all these are things to measure time. Time is a dimension, I understand in simple language, time has been moving ever since our universe was created, so is time moving us? No, things keep changing with time, meaning motion also keeps on changing with time, see like ever since the universe was created, it is expanding and all this is happening with time. Before the Big Bang, there was no motion in the singularity, so there was no time then, it can be said as if only time can be the cause of change. Times are changing. Why we should not make contact with aliens right now Great scientist Stephen Hawking said that we should not make contact with aliens right now. Why did he give such advice? Because we humans are still like small children in the world of technology, you will say that science has progressed so much, so many discoveries have been made, we have even gone to space, once or twice in space. We do not become rich by leaving, we have not even searched for living on another planet or have gone to live on any other planet. This progress seems big to us but it is nothing. If we contact any alien civilization, they will reach our Earth and may even harm us, that is why even today we do not respond to any signal. Quantum Elevator What is a quantum elevator? Suppose you are in a building and each floor of this building is a different dimension, you live on the 4th floor, that is, in the 4th dimension, and you have to go from the 4th floor to the 10th floor and there is an elevator here which will take you there. But when you are going from 4th floor to 10th floor then you will not be able to see the floors coming in between and you will not even know what is on this floor. This is how the quantum elevator works. And this can be very different in different dimensions, it takes us in a fixed dimension. Bennu Asteroid Composition: Bennu is a carbonaceous asteroid, rich in carbon-based compounds. This composition makes it valuable for scientists, as it could provide insights into the origin of life and the early solar system. Sample Collection: NASA's OSIRIS-REx mission successfully collected a sample from Bennu's surface in October 2020. This mission aims to return the collected samples to Earth, allowing scientists to study the asteroid's material in detail. Impact Risk: Bennu is classified as a potentially hazardous asteroid due to its orbit's proximity to Earth's orbit. Scientists continue to monitor its trajectory to assess any potential impact risks in the future. Images Voyager's Golden Record The Voyager Golden Record, a time capsule of humanity's cultural and scientific achievements, was launched aboard the Voyager 1 and Voyager 2 spacecraft by NASA in 1977. This phonograph record contains a diverse array of sounds and images representing Earth and its inhabitants, including greetings in 55 languages, music from various cultures, and images depicting life on our planet. The record was designed to serve as a message to any extraterrestrial civilizations that might encounter the Voyager spacecraft. A testament to human curiosity and creativity, the Voyager Golden Record remains a symbolic representation of our species' desire to reach out and connect with the unknown, even across the vastness of space. Gallery WARP Drive Warp drive is a theoretical propulsion system that features prominently in science fiction, notably in franchises like "Star Trek." The concept involves manipulating space-time to enable faster-than-light travel, allowing spacecraft to travel vast interstellar distances in a relatively short time. In essence, warp drive contracts space in front of the spacecraft while expanding it behind, creating a warp bubble that moves the vessel. While widely popularized, especially by theoretical physicist Miguel Alcubierre's theoretical framework in 1994, practical implementation remains a distant dream due to the enormous energy requirements and unresolved challenges in bending space-time as proposed. Scientists continue to explore the theoretical underpinnings of warp drive, but as of now, it remains firmly in the realm of speculative science fiction. Psyche Asteroid Psyche is a massive asteroid located in the asteroid belt between Mars and Jupiter. It's of particular interest to scientists because it's composed mostly of metallic iron and nickel, resembling Earth's core. This unique composition has led researchers to hypothesize that Psyche might be the exposed core of an early planetesimal, offering a rare opportunity to study the interior of a planet-like body. NASA's Psyche spacecraft, slated for launch in 2022, aims to explore this intriguing asteroid, providing valuable insights into the processes that shaped the early solar system and potentially uncovering secrets about planetary core formation. Earendel Star The James Webb Space Telescope has discovered the most distant star in space, which is believed to be the most distant star ever explored, and it is also believed that this star was formed only in the first 100 million years after the Big Bang. had gone Arandale was discovered by the Hubble Space Telescope in 2002 and along with its expansion, it has moved 2800 kilometers away from us. Recently, NASA has once again discovered this star with the help of James Webb Telescope and it has been revealed that it is 2 times bigger than our sun, its brightness is 1 million times more than our sun. NGC 6166 Black Hole Psyche is a massive asteroid located in the asteroid belt between Mars and Jupiter. It's of particular interest to scientists because it's composed mostly of metallic iron and nickel, resembling Earth's core. This unique composition has led researchers to hypothesize that Psyche might be the exposed core of an early planetesimal, offering a rare opportunity to study the interior of a planet-like body. NASA's Psyche spacecraft, slated for launch in 2022, aims to explore this intriguing asteroid, providing valuable insights into the processes that shaped the early solar system and potentially uncovering secrets about planetary core formation.

  • Osiris-REx Mission | SPACELIA

    Osiris - REx Mission Remember that scene in "Armageddon" where Bruce Willis blows up a giant asteroid on a collision course with Earth? Thankfully, Bennu, a real near-Earth asteroid, isn't hurtling towards us quite that aggressively. But it is still a celestial wanderer with a thrilling story, and the audacious mission of the OSIRIS-REx spacecraft to unlock its secrets. Bennu: A Time Capsule From the Solar System's Dawn Imagine a colossal rock, bigger than the Empire State Building, older than the dinosaurs, and potentially holding the key to the origins of life on Earth. That's Bennu, a carbonaceous chondrite asteroid formed in the fiery crucible of the early solar system, some 4.5 billion years ago. Unlike its metallic or rocky siblings, Bennu is a carbonaceous treasure trove, its dark, diamond-like surface coated in organic molecules and minerals untouched for eons. Studying these pristine materials is like opening a time capsule, offering scientists a glimpse into the conditions that gave birth to our solar system and the potential for life beyond Earth. OSIRIS-REx: A Touch in the Void In 2016, NASA embarked on a mission as daring as it was groundbreaking: to rendezvous with Bennu, study its surface, and collect a precious sample. The OSIRIS-REx spacecraft, a technological marvel resembling a robotic octopus, embarked on a years-long journey, navigating the gravitational dance of the solar system and finally arriving at Bennu in 2018. For two years, OSIRIS-REx orbited Bennu like a celestial dance partner, mapping its surface in exquisite detail, revealing a world of craters, boulders, and even a mysterious dark plume erupting from its surface. Then, in October 2020, came the moment of truth: the Touch and Go Sample Acquisition Mechanism (TAGSAM) extended from the spacecraft, gently kissed Bennu's surface, and collected a handful of precious regolith (loose, rocky material) – Bennu's ancient secrets scooped into a cosmic treasure chest. Mission Accomplished: Bennu's Treasures Return to Earth After successfully completing its mission, OSIRIS-REx began its long journey back to Earth, carrying its priceless cargo. On September 24, 2023, the spacecraft hurtled through the atmosphere, releasing the sample capsule over the Utah desert. This precious payload, containing millions of Bennu particles, landed safely, marking a historic moment in space exploration. Bennu's Secrets Unlocked: A New Chapter in Science Scientists around the world are now eagerly analyzing the Bennu sample, hoping to answer some of humanity's most profound questions. What were the building blocks of the solar system? How did asteroids contribute to the formation of planets? Could Bennu's organic molecules hold the key to the origins of life? The answers lie within the grains of Bennu's regolith, waiting to be deciphered. This mission is not just about understanding the past; it's about preparing for the future. Studying Bennu's composition and trajectory could help us develop strategies to deflect asteroids in case they ever pose a threat to Earth. Bennu: More Than Just a Rock, a Story of Our Universe The story of Bennu is a testament to human ingenuity and our insatiable curiosity about the universe. It's a reminder that even in the vast emptiness of space, there are treasures to be found, stories to be told, and mysteries waiting to be unlocked. With every grain of Bennu analyzed, we expand our understanding of the cosmos and our place within it. Who knows, maybe one day, Bennu won't just be a celestial bullet dodged, but a key to unlocking the secrets of life itself. Other Articles......

  • Hubble's Star Clusters | SPACELIA

    Hubble's Star Clusters Billions of trillions of stars illuminate the galaxies of our universe. Each brilliant ball of hydrogen and helium is born within a cloud of gas and dust called a nebula. Deep within these clouds, knots can form, pulling in gas and dust until they become massive enough to collapse under their own gravitational attraction. Open Clusters Open clusters contain between a few dozen and a few thousand stars, all formed from the same initial cloud of gas and dust. The density of stars is low enough in these clusters that individual stars are visible with a telescope, or sometimes the unaided eye, giving them an “open” appearance. Most open clusters reside in the arms of spiral galaxies, and their stars are usually relatively young. Their shape is more irregular than spherical, with large amounts of gas between the stars. Over time, as these clusters rotate around a galaxy, gravitational disruptions from passing cosmic objects can cause the stars to disperse. The Milky Way is home to more than a thousand of these clusters, and even our Sun may have formed in an open cluster. Globular Clusters Embedded Clusters Globular clusters are much larger and denser than open clusters, containing several thousand to millions of stars all formed from a shared nebula. Unlike open clusters, the density of stars at their centers is so high that individual stars are hard to discern, even with powerful telescopes. Globular clusters lie on the dusty outskirts of galaxies and their stars are older than those in open clusters. In fact, globular clusters contain some of the oldest known stars in a galaxy. Because old stars tend to have a reddish glow, globular clusters generally appear redder than open clusters. The large number of stars in a relatively small area causes the shape of a globular cluster to appear spherical, as stars’ intense gravitational attraction pulls them together. These gravitational ties grant globular clusters more stability than open clusters, helping them keep their structure instead of breaking up over time. The Milky Way alone has over 150 globular clusters, and our nearest neighboring galaxy Andromeda has over 400. Embedded clusters are a precursor to open and globular clusters. As the youngest type of star cluster, they contain newly born and forming stars surrounded by cosmic gas and dust. As with open and globular clusters, all of the stars formed from the same initial nebula. Embedded clusters are likely the basic unit of star formation since a significant fraction of all stars form within them. Once star formation ends, embedded clusters resemble open clusters, but are often disrupted by passing objects due to their weaker gravitational bonds. The embedded phase typically lasts between 2-7 million years. Since embedded clusters are heavily obscured by dust, they are rarely observed in visible wavelengths of light. However, Hubble’s infrared instruments can detect the longer wavelengths of infrared light that aren’t as easily scattered by clouds of gas and dust. Hubble’s unique capabilities are essential for learning more about these young clusters.

  • Today Onward Theory | SPACELIA

    What is Today Onward Theory?, This is a theory that will shock you, I will explain this theory today but only if you can relate to it then you will be able to understand it, I have given my strong point of view in this.

Over View.... What is Today Onward Theory?, This is a theory that will shock you, I will explain this theory today but only if you can relate to it then you will be able to understand it, I have given my strong point of view in this. What is science?, Have we made much progress in science?, How will science be in the future?, Can we become a Type 2 civilization?, you will get the answers to these questions later, but let me say one thing that if today's From the point of view, science has not done anything, according to scientists, if we want to become a Type 2 civilization, then we still have a lot of research left to do, now you will say that we have discovered so much in space science, how much more?, let me tell you. We are not going to become great by going to space or going to the moon 2-3 times, because we do not even know how to take people out of the solar system, we have not even reached Mars, nor have we established our colony on any planet. If it has been made, then how can we say that science has progressed a lot. One step towards the future Now if you say, what do we have to do so that we can progress?, and where is science today? You will get answers, all your questions will be answered, if you have any question after reading this theory then you can tell me in the chat box below, I will answer all your questions. So what is my point of view, I will tell you, if we have shared something before, then where are we now?, right now we have definitely made a lot of progress in science but that progress is not enough, if we want to become a Type 2 civilization then there is still a lot of work to be done. The journey is still left, all the space we have traveled in comes within the solar system only, we have only taken people to the moon, and for the last many years we have not even been able to send humans again, if you look at science. It has made considerable progress in the last 100 years, but is it enough? No, if we want to reach Alpha Centauri, the system we have today, it will take thousands and millions of years, and we will never be able to reach the nearest galaxy. Then how can we say that we can become a Type 2 civilization? Now I will explain my point of view to you by listening to a story, "Once everyone was present in the king's court, then the king said to a minister that I am very happy with your work and want to give you a gift, tell me what do you want, minister. He was as intelligent as all of you, he said, King, I don't need much, just one square of Chokha in the first square of a chess board and its double in the next one, give me as many Chokha's dens as will be made in the last square, King. The king ordered to give him whatever he wanted, then a servant came and said that the king has asked for so many grains that there are not so many of them in our entire kingdom, then the king was very impressed by him, you will think how many grains would have been there which the king would have given. If I couldn't give it, then I have counted it for you all, and it comes to more than 2305843007575253120, and this is so much that its count has not been discovered till date, and this is exactly how our space science is progressing. , How progress is doubling every day, NASA has been established for only about 70 years and how many discoveries have been made in these 70 years, ISRO was also established 60 years ago and how far it has progressed, in the coming 10- Science would have advanced a lot in 20 years, just take the example of A.I. Most of the people would not even know about A.I before 2020 and it has increased in just three years. In this way our science is progressing and will continue to do so. Chat Section....
